Noob fish tank owner here! Wonder if anyone can help, I've recently bought a Biorb cube 30 litre and have been researching fish etc I'm after a combination of small/nano size fishes and that can live with a heater or not depending? Ideally i would want 1 catfish, 1 shrimp, 1 pea puffer and any other fishes that'll fill up the rest of my space. I need help as every website is saying different. I know 30 litres isn't a lot to work with but I'd like to make the best out of my situation. Thanks

Hi all ive decided to get a peacock mantis shrimp and give it its own tank. I found an old oceanic 8 gallon bio cube on Craigslist for 35$ and was thinking of using that. It fits perfectly on my nightstand. I also have a 20 gallon setup that I took down a few months ago when I upgraded. But it is a budget 20 gal setup and not exactly quiet or pretty. I think 8 gallons could be big enough for a mantis shrimp if I provide it with lots of burrowing spaces and a deep sand bed. What do you think?

So it’s been 6 months into my Reefing career and everything is running smoothly on my 29g sumped mixed reef.I decided to build a Pico Jar Reef. Running on nothing but bubbles, a light, and a heater.Equipment used:Fluval Q.5 PumpDeep Blue 7.5w heaterAbi 12W Par38 Tuna Blue LED Bulb2 gallon Anchor Hocking glass jarBiological Equipment:3lbs live rock5lbs live sandAssortment of corals, list will be put together as the cycle is being established.Stay tuned!

So after my first tank I am now very much addicted to this hobby. I currently have a tank that is just slightly over 60 gallons... but it isn't enough! There are still so many fish I want ;___; Woe is me. So I am considering in a few months maybe starting up another smaller tank. I'd love a larger tank but I honestly think our landlord might actually kill me if I did (he said when we signed the lease that he didn't care about anything in a cage/tank, only about cats and dogs, but I don't think he expected our tanks to be a 55 and a 60.... I think he was thinking more along the lines of a 10. Luckily it doesn't have anything against fish tanks in our lease...) We have a LOT of extra tanks in storage at my boyfriend's dad house ranging from 10's to 60's... I'd love to take our 40 hex home and make that a saltwater but we don't really have a spot for it, so I was thinking either a 20 long or maybe looking around to see if we have a 29. If not, Petco's $ per gallon sale gets me one for $30 bucks so... not too bad. I have plenty of sand and crushed coral substrate from my 60, so that should be essentially free to fill a new tank with substrate, and I think I can probably get the live rock for free (or at least several pounds), and if not then it is only around $3/lb for me since I work at a local fish store. Saltwater is also free for me. So would all I have to pay for essentially be a filter, heater, light, and circulation pump? Do I even NEED a circulation pump in a smaller tank, or would that mainly be useful if I put corals in as well? How many of you use skimmers, or would recommend doing so, on a 29 gallon tank? I really in particular would love to have a white banded pygmy wrasse and a gumdrop coral croucher. Also maybe a longnose hawkfish or something, I adore hawkfish... either way, any recommendations on starting up a small tank? Am I underestimating the cost? I know my larger tank cost a decent amount to set up, but I had to purchase a skimmer, the substrate, rock, etc... what would you guys recommend for lighting as well on the 29? I would also need to have a cover on it, since we have 3 cats that I don't trust, and wrasse are my favorite things in the world so the tank is bound to end up with a wrasse in it somehow... Does 4-5 small fish seem about right for a 29 gallon? Any input you have is certainly welcome! I can't afford to do this until after probably January but it never hurts to start planning

Hello all. Quite a few years back I was heavily involved in the reefing community and had a 180G reef/fish/coral tank up and running for a few years. I ended up buying a house and getting married so I ended up selling off everything so I could make the transition a bit easier. Now I have been divorced for 2 years and decided to get back in. Slowly. This is what I had sitting in the basement.

Build thread of my nuvo 10 gallon all in one reef He's pics of live sand and dry rock not sure my approach on cycling this tank yet Water is in thoughts on a quick start additive and a clown fish? I know it's not proper I have ran a 65 gallon mixed reef cube for the last 3 years parted ways so I'm not new to the hobby but wanted to hear some options

My Seabae anemone is in a 125 gallon aquarium and I was wondering what the size limit is on that anemone in such a big tank

Are there any other blueline-pipe-type options out there? Dragonface pipes are the only one I can think of (in the trade) that are close... Bluelines are so unique and one of my fav fish and I would love to expand on this niche that I rarely hear about. Thanks, S
