Pseudoshrub Posted January 27, 2015 Share Posted January 27, 2015 Just want a second opinion. Critter 1. I found this guy attached to a rock earlier. It looks like some kind of a sea cucumber? Any ideas? Critter 2. Is this one Aiptasia? If it is then my two Peppermint shrimps aren't doing their jobs. Critter 3. What are those black things growing on the rock? Kind of a looks like micro blueberries or something. I've yet to see any kind of a movement. Suggestions? Critter 4. This one I found swimming about in the dark, as soon as I turned on the lights it darted to the sand and started burrowing and boy could he dig, I'm thinking amphipod. 2 small black eyes, slightly transparent white body. Suggestions? Link to comment
atrox Posted January 27, 2015 Share Posted January 27, 2015 Last one could be isopod. Get it out of there. Not aptasia looks like a majano. Sea cucumber? Get a better shot. Blue berries? Could be bubble algae. Better closer photo. Link to comment
Pseudoshrub Posted January 27, 2015 Author Share Posted January 27, 2015 I should mention that the tank has a very bad green hair algae problem, there's also bubble algae, however I'm pretty certain the "blue berries" are not bubble algae. I'll try get a better photo if I can. Here's a photo of critter 1. Link to comment
GHill762 Posted January 27, 2015 Share Posted January 27, 2015 my guesses 1. baby sea cucumber or sea apple 2. agree looks like mojano 3. looks like closed up sympodium coral 4. ? Link to comment
jamescstein Posted January 27, 2015 Share Posted January 27, 2015 1) filter feeding cucumber 2) majano, still a pest, but not aptasia 3) look like tunicates to me 4) Can't tell really from that pic, could be an isopod If it looks like this.. then its an isopod, get it out. http://s1247.photobucket.com/user/nietssemaj/media/Aquaria/ID/D2045756-60F4-4D5C-B13A-4752544587B8.jpg.html'> Link to comment

I'd agree with you on 3 if I didn't have sympodium and know what it looks like closed up, and it looks exactly like that when its pissed off. Link to comment

Yeah its an Isopod, sigh... how to remove? is there a trap or something i could use to bait them out? Link to comment
jamescstein Posted January 28, 2015 Share Posted January 28, 2015 You could make a bottle trap. Take a plastic soda bottle, cut it in half (top/bottom). Invert the top, put a piece of shrimp/fish in there and drop it in your tank. You might also drill a hole in the cap and put the cap on as well to keep larger stuff out. Not sure if I've caught any isopods that way though. I have caught my brittle stars and a few gorilla crabs with one. I find it easier to just go in after lights out (moonlights only) or before the lights come on in the morning and looking for them, they are usually swimming around on the glass. Likely looking for food. I have nothing in the tank but some inverts now so I am sure they are hungry. I suck them out with a turkey baster. They are fast and photo reactive so you can't turn lights on. They don't seem to be able to see red, but I can't see well in red light either. My moonlights provide enough light to see them.

GHill762 Posted January 28, 2015 Share Posted January 28, 2015 can you get a closer pic of #3? Link to comment
amphipod Posted January 30, 2015 Share Posted January 30, 2015 100% sure no 1 is some sort of sea cucumber, fine when they are small. Yeah its an Isopod, sigh... how to remove? is there a trap or something i could use to bait them out? now hold on with the kill switch, there are hundreds of species of isopods you can encounter in tanks, most are harmless detrivores, some can be parasites though. I'd recommend you show me a pic before you go killing potentially beneficial animals.Number 3 looks like tunicates, make sure to give food if the water is very crystal clear. If they have been there a very long time though, they should be fine. Also watch out, I had tunicates them Kong my gorilla crab and his friends turned on them, always isolate crabs from sessile organisms. 2 is with all certianty not aiptasia, aiptasia has no bubbles on the tips Link to comment

I fashioned a bottle trap and caught two of those isopods then sent them on their merry way. Yeah I'll see if I can get those tunicates healthier. I'll also try to avoid crabs. cheers Link to comment
amphipod Posted February 5, 2015 Share Posted February 5, 2015 Good thing you got a few cool new species in the tank Link to comment
