Hi does anyone have an ideas as to what this is? The two antennae are actually part of the critter itself, whereas the rest of the spiral-structure is the “home” it builds (which is quite hard / like a shell — about 1cm diameter).
obv my first concern is whether they’re harmful or just...
I’ve had this guy as long as I’ve had live rock (almost a year). He’s big, ugly, and I’m pretty sure he’s trying to reproduce in my tank. Slithers around on my rocks and eats algae, I haven’t had an issue with him yet. What is he??
I was looking at my tank tonight and i noticed these little "Worms" crawling on my sand... Then I realized, they are all coming form the same place. I gotta dig see what critter is in my tank now, as I am kinda protective of it to be frank! :) I'm certainly no Paul B that's for sure, more of a...
My LFS told me that I had an isopod in my tank based on a video I showed them. I think this is the same critter, can you tell me what this is?
*IMPORTANT EDIT* and if it IS, could there be more?????
Still as yet Unidentified purple live rock hitchhiker is translucent, reactive to light and danger from other creatures, will turn almost solid white when withdrawn near the entrance to its hole in the rock.
Two for one here:
Question 1 is what are the eggs pictured below from? They are all over the place. I have searched for a few days now and cannot find an answer. It is about 3/16" or 5mm.
I have introduced 2 Astraea (I believe, pictured below), ~18 Cerith snails and 6 dwarf blue leg hermits...
I found this weird anemone with a brown foot/stem and purplish blue tipped tentacles. It was on some Indonesia ocean cultures live rock. The rock has been there for about four days and when I looked at the anemone earlier it was small, just now it became bigger.
A smaller one
I found this little green dot looking thing on my sandbed in a low flow area today. It was sitting there before I placed it in a cup with sand at the back of my tank. It’s about the size of a nerd candy, neon green and I can see a spot without green which I assume is the foot, if it’s a...
Would love some guidance on what these are on my live rock. If you need better pictures or different angles let me know and will try my best.
Good Morning all,
Got home from a trip late last night and wanted to check on my ATO and such before bed. Was completely dark in the room and tank when I got in, and I saw a few of these little bugs moving about. Seemed to be eating the glass algae. After a 20 minutes or so they all seemed to...
Any ideas what this thing is? Its been moving slowly for the past few weeks, started out along the base of the coral and I missed it - its currently on a mushroom finger leather coral... Survived a coral dip...
Is it harmful?
what do I do with it?
Hi I found this worm living under my scoly. Is this a normal bristel worm or something bad like fire worm? How can I remove them? Any fish that is good? I have tried fit trap, it doesnt work that well. Thank you!
Hello. Wondering if someone would be able to assist me in identifying this. It looks like aiptasia but I cannot be sure as most of the pictures I have seen appear to have a larger disk.
Thanks for the help!
I recently noticed that a frag of green mdntipora had a small area where the flesh was gone and the skeleton was exposed. It had soon before i noticed this fallen from it's spot, so I thought that it had possibly been damaged and the flesh had simply fallen off. I kept an eye on it, and a week...
