  1. Wondering what this brown stuff is on my coral. Not sure what coral it is as I bought the whole rock as a piece off another hobbyist. i have a bit of brown algae in my tank however this has gotten smaller and lost colour. All of my peremiters are well my nitrates are about 20ppm. any help would be appreciated, I’ve posted in other forums and haven’t gotten any advice. thanks

    Is my coral happy?

    I just got my first coral, it’s spotted mushroom from live aquaria. I’ve read their instructions on placement and water flow, but I’m wondering, how do I know if these corals are happy/doing well? How do I know if I should move them to a different place in the tank?

    Lighting questions and acrylic lid

    Hi all, First, a huge thank you to everyone on this forum that has been so helpful to me with all the posts I’ve made. Your advice has been crucial as I have been learning more about this hobby. I want ant to ask about lighting. A month ago I picked up someone’s used 32 gallon biocube that they had modified. They removed the canopy and replaced it with a mounted vivaspectra led light and a mesh cover. Recently ive been looking to change that setup since evaporation has been requiring me to add fresh water to the tank twice daily to maintain salinity. It’s impractical to have to use the RODI machine that often and so I built myself an acrylic cover to replace the mesh lid. I want ant to know if this will affect the light that reaches the tank. Does anyone have experience/ is it a good idea to run light through an acrylic panel and still grow healthy corals? aditionally the light is adjustable and can dim the 10k whites and actinic lights independently and im trying to decide what ratio of the two will be best for growing my corals. A few montipora, some acans, a couple chalices, and Zoas are the corals I’m currently growing. Assuming I have the right placement for each what spectrum of light is ideal to help them grow? More blue or more white? Will the acrylic lid affect how this ratio reaches the corals? any advice is deeply appreciated!

    Parasite on my acans?? Help? (Pictures)

    I dont know what this is but it seems to be growing or living on the side of my acans. Will it hurt them?? Ignore my serpent star. It seems to have two tentacles/antennae?
  5. I bought this three-headed frag of acans 2 days ago. They seemed pretty happy until now. I even fed them some frozen mysis last night. but there was always this one corner that seemed to be releasing a little bit of slime into the water. That'ss what corals do when they've recently been disturbed and moved" I said to myself, and I assumed it would just wash away. Then today I got back from work and found that corner oozing lots of slime and can see some exposed skeleton! the other heads seem very happy; no recession as far as I can tell. And even the oozing head seems happy besides. But something is clearly wrong. Did I tear the polyp pacing it in the tank? Is it infected? can I blame this on water chemistry and lighting? I need a diagnosis and I feel like I need to act fast based on how suddenly this injury appeared.

    Acan Echinata: How fast does it grow?

    Thinking of buying a decent sized colony of Acan Echinata on sale at my LFS. Does anyone know how fast this coral grows? With/without feeding? Is it hard to care for? Basically any advice? Is it ok for someone with beginner to moderate experience with corals? (I’ve been keeping Monty Cap trumpets and frogspawn successfully for a few months)

    Coral ID

    I've recently aquired my first marine aquarium which came as a full set up, including this coral which seems to be doing quite well. Can anyone identify it for me? Its about 6cm across currently. Also be interested to know how large and how fast it is likley to grow, and whether it will benifit from the soft coral powder food i'm adding for the other corals. Thanks in advance

    Any high flow corals

    I have a biocube 14 with upgraded LEDs and a wave maker which does 144 gph flow. I have 4 coral colonies which are thriving The corals are Red Cap Monti (doubled its size in 4) Recently got an uknown stylophora which was in a low flow tank in Petco and got it for FREE (started growth on a new branch) Duncan coral (is growing 3 more heads) a yellow birds nest coral (also doubled its size) my cuc is 4 hermit crabs and an astrea snail. And centerpiece is a domino damsel I'm looking for 1 more easy to keep coral as I don't want to push the bioload. Any Ideas
  9. (I posted this same post in the corals forum) Hi. I'M new to the forum and was hoping some experienced reefers could offer some advice on my coral health! I have a 20 gallon DIY mixed reef tank that has been running for about 6 months. I have about 1 year experience running a 75 gallon reef tank that I took down about 6 years ago when I left for college. Everything I have added (soft corals, LPS, fish, inverts, nem) seems healthy and has been a pleasure to watch. Up until now I have never tried any SPS corals. 5 days ago I decided to venture into some "beginner" SPS. I don't have very accurate water testing kits so I am not looking to advance any further with difficult corals until I can at least better monitor my water parameters. I have a very large amount of live rock for the tank size and two hang-off-the-back filters (in case one ever fails). My heater is a decently stable and my digital thermometer always reads 78.4-78.8. My lighting is not very strong: Marineland LEDs rated at about 100 par at 12 inches and 6000K. It is also not diffuse at all and has almost spotlights of higher intensity throughout the tank. (yes, I plan to upgrade my lighting when I have the funds in about a month). I bought two montipora frags 5 days ago, one large orange monti cap and one small sunset monti. Both came from my LFS and were not shipped (at least not any time recently). To compensate for my low lighting I placed them about 5 inches down in the water directly under the "spotlights" from my LEDs. I really don't know enough to tell if they're doing ok or not. given that my situation is atypical bordering on stupid (I know it sounds bad) I want to make sure Im not killing the frags. I have a friend with a very successful SPS tank who will take them if I'm hurting them and I just don't want to see them die! I think they might be doing ok. I'll be watching for long term signs of health but I just wanted to ask if there are any issues visibly indicating immediate shock from new/bad tank conditions. Please don't be too hard on me. I know you'll want to know my water parameters and more details than I can probably measure. I don't want advice on keeping them alive as much as advice on how to tell if they're healthy (although all input is appreciated). If they aren't healthy I will rehome them at the first clear sign they're declining. I have attached pictures.

    New Chalice Frag Dying?

    I have a 20 gallon tank that has been set up for about 6 months and have been having great success with soft corals so I decided to pick up a trumpet coral and chalice frag 2 days ago. The trumpet seems happy but the chalice looks concerning. I know they don't like a lot of light while they adjust so it is at the bottom of my tank out of the direct light from my led lights (they are not particularly strong anyways). right away i noticed a little bit of brown discoloration on the side of the coral. over the couple of days I've had it the brown area seems to have become more distinct although no skeleton is exposed. I know there's a lot of variables at play (water params, parasites, lighting, handling) but what I want to know is whether this is a sign of a serious problem. The brown spot hasn't really progressed noticeably in the last day so is it a cause for concern? Although I do want to know why this happened I'm more concerned with just knowing what is happening and how worried I should be.

    Bleaching/death rates of corals

    Hello everyone, I want to learn about some ways in which a coral might bleach or die. I am particularly interested in bleaching/death rates for each reason. As an example, I believe bleaching due to low light intensity might take a couple days while excessive light intensity might kill a coral much faster. Does anyone have a refference for all possible death rates of corals? Although I'm interested in sps corals, information on every coral would helpful. This could help use better make an idea on why our corals might br struggling. Thanks!

    Montipora Digitata polyp extension question

    I recently got my first SPS frag, a blueish Montipora Digitata. Now, with my other corals, I could get a decent enough idea if they were happy or not concerning flow and lighting for example, because their response was quite obvious and quick (Euphyllia and Rhodactis for example). However, this being my first SPS, I am not so sure, so I figured I'd make a small thread, hoping you guys and girls could help me out. As for my parameters, I measured these this morning and the frag is in my system for about a week; Ammonia: 0ppm Nitrite: 0ppm Nitrate: ~3ppm Phosphate test kit is on its way PH: 8.2 dKH: 11.3 Calcium: 475 Lighting: AI Prime HD on a somewhat customized AB+ schedule and on an acclimation period until February 23 Flow: return nozzle and Aqamai KPS Left side view right side view Close up (crop) where the polyps seem to extend the most I am not entirely sure yet about the placement, because I see a lot of shading/dark sides on the frag, which is a result of the shape as well. I am also wondering if I could accidentally burn it, having it so high up on the rocks, that's why I put the Prime on an acclimation period though. Last but not least, my apologies for the quality of the images. They were made with my phone, yet I am looking to buy a filter and magnifier soon, because I really enjoy taking pictures of the frags and how they're evolving/growing. What do you guys and girls think? Polyp extension alright, or no? Anything I could or should change, any feedback is much appreciated! Bonus question, is it normal to tweak that much in the early stages of having a reef aquarium? I just can't seem to let it be, instead, I am wondering if the light schedule is alright, what about the placement of the frags....Flow, wondering if the return nozzle is aimed alright and the KPS schedule is decent enough....Oooh, how about the turnover rate? 🤦‍♂️ (I am really enjoying it though, don't get me wrong, haha!)

    MUSHROOM CORAL SHRINKING

    Hello guys, About two years ago, I picked up a green rhodactis mushroom from the reef store. As soon as I put it in my tank, it spread out very wide and became very colorful. I continued to love the coral, and it kept growing until it doubled in size and became as large as the palm of my hand. It kept on flourishing and growing like this for about a year. Then, I noticed it wasn't coming out as much and I took some observations and did some research and found out that it was going to split, and it did. So then there were two mushrooms, but it just continued to go downhill from there. They shrank very gradually and lost their color, but I figured it was just a small phase and did nothing about it. Now, a year later, one of them has disintegrated, and I have one left about the size of a penny. It's not colorful anymore. I miss how it was two years ago 😭 Water parameters have not drastically changed at all, I just don't know what's wrong. Please help
  14. first off i want to find out what kind of coral i bought a while back. im just curious. and also i just finished feeding phytoplankton to my corals and are now feeding reef-roids. out of curiosity should i find a new coral food or maybe should i have any advice with food i currently feed them. Note: [my tank is a little cloudy because i just finished feeding and accedentally overloaded the food. lol, my bad] the coral is in the shell

    Adding first corals?

    My Biocube 32 has been cycled for around three weeks, I added the first members of the CuC crew two weeks ago, and the first fish, a royal gramma, several days ago. I want to buy my first, hardier coral soon. Can I do it now, or would it be best to wait? Also, what would people suggest as a first coral? I've looked at green star polyps, mushrooms and others, but I'm curious what others would advise.
  18. I have a 10 gallon nuvo cube and a kessil A80 light, I just got two clowns, two hermits, and 4 lps soft corals. I was wondering what should my light schedule be like? And the intensity and so forth. Right now as I’m going to bed I have it at 0/0 but I’m not sure if that is okay for coral? Please HELP!

    Can someone ID this coral?

    Hey guys, sorry if this is an obvious or stupid question, but can anyone properly ID this coral that I bought? It was sold to me as a long armed plate coral I believe, but I feel like it’s something else? Thanks!
  20. So as you can see in the title I have finally broke down and bought a Red Sea max 170 with the sump upgrade after I saw that my LFS was doing a 15% discount on them. But I haven't filled this tank yet but I will probably buy some water to fill later today, this is MY first tank, but I helped take care of one at the LFS I help out at. But basically I know I want corals, there my favorite thing in the reefing hobby. I will probably keep the Red Sea skimmer in the back chamber along with the media basket then in the sump upgrade I will most likely do a refugium. The light is a AI hydra 26, and I might get a MP-10, if not I might just get 2 korelias to tide me over till I get the MP-10. So now that you all know the equipment im running im wondering what livestock I can keep. Coral -GSP (separate rock) -Finger Leather -Toadstool -Zoas -Hammer -Frogspawn -Candycane -Elegence -Possibly acans -Later down the line a Monti cap or two. -And then any other corals that I might find interesting later down the line. Fish (I order from what will be added last to what will be added first) -Pair of Occ. Clowns -Yellow corris wrasse (favorite fish) -Yellow clown goby -Pearly jawfish Inverts - 3-4 Narrsarius snails - 3-4 Trochus snails - Cleaner shrimp Clams (later after tank has matured) -1 Maxima -1 Deresa The tank is about 24x24x24 Any thoughts much appreciated

    Twizzler Zoanthid help

    Hi all! This is my first post on here but I’m looking to find some help with my recently bought twizzler Zoas! About three weeks ago I purchased a twizzler zoa frag and since then it has not done well in my tank. It started off with five polyps that looked healthy and it has now depleted to 2 maybe 3. I tested some water levels yesterday and I got these results: Alk: 120 ppm Ph: 8.0 Nitrite: 0 mg/L Nitrate: 20 mg/L I also tested salinity and it was a little salty so I did a slight water change and fixed that. I have been feeding it benepets reef food twice a week since I’ve purchased it. I currently have it in my 13.5 gal fluval evo that also contains two emerald crabs, a condylactis anem, and a GSP coral. The only sign of damage toward the zoa was an accidental pinch from my emerald crab early on as a piece of mysis shrimp landed on the zoa and the crab accidentally pinched and sorta mutilated one of the polyps while grabbing the food. I don’t know what else to do but I really don’t wanna lose this guy, please help!

    Scolymia as first corals?

    Hello, I am pondering on some corals of interest to populate my tank. I am not the biggest fan on soft corals and I am considering some zoas or maybe mushrooms, but I plan my tank to be filled mostly with sps. Since I am a long way before that, I have been quite interested in Australian Scolymias, but I am wondering if they are good candidates to some of the first corals in a tank. I have been reading about this beautiful corals and they appear to be easy to take care of given the right conditions. Considering the prices that these corals can get, I do not want to buy one just to kill it. What do you guys think? are Australian scolymias a good first coral? Thanks!
  24. i have visited my LFS and saw some majestic pakistani butterfly fish or red tail butterflyfish now correct me if im wrong but there are NOT REEF SAFE so i wanted to know how i may be able to house them together with minimal damage to corals

    Name This Coral!

    Hi - recently picked up these two frags but I have no idea what they are! Ones a birds nest - seems like a yellow green color (seriatopora I think) but not certain of the other acro. It’s a dark green. Trying to figure this out so I can provide the best tank placement. Thanks for your help! (The lighting doesn’t do the color justice)
