Found this when I turned on the light today anybody know what it could be??

Anyone please if u have any suggestions. Hello,i recently set up a 30 gallon saltwater tank. We put base rock and a few pieces of cured live rock in the tank to help cycle. It's now going on almost three weeks and I have noticed in one of my caverns in one of my rocks this clear like anemome or...

Hello All:wavey::wavey: Looking to buy some live rock to help seed my tank, but I am very worried about introducing pests and parasites into my tank. Anyone have personal experience buying live rock in South Florida? Thanks for the help!! :D

so I was looking for an aptaisia that I had seen growing in my tank that I havn't managed to remove (not what im worried about here). I saw this little clam like guy moving across my live rock... was just wondering if anyone can give me some insight on to what he is and if he needs to be removed...

:wavey:Help:confused:

So this little guy came on my live rock but it seems like it's probably a little too far gone to be saved. Should I just take it out or let it stay and see if I can save it?

Not really sure if this guy is good or bad..I'm new to the community and hobby. Any info is very much appreciated!

A new crab just showed up in our tank from a live rock which is a couple months old. He lives under an oster. He/she has hairy legs and black claws. I have tried to get pictures but he is shy. I believe he is a gorilla crab. Currently he is about an inch in diameter including his legs and...

I've had this tank for like 5 months, I stare at it all the time and never seen these. Any body know what theyes are, good or bad?

Today I bought a small rock with a few mushroom polyps on it from my LFS. Upon getting home and inspecting the rock for hitchhikers, I found this guy. He's acutally pretty big, his body is about an inch long. He has striped legs, and looks somewhat similar to my emerald crab, except this one...

I have been doing some aiptasia and hydroid demolition today and found some new boogers that are interesting and I was going to see if anyone knows what they are. It's amazing that after 2 years, there are still new things popping up out of nowhere. The first pic shows a colony-like group of...

Hey Im new to the forum, just recently started keeping a salt water aquarium. I got some soft coral today and i found this slug on it, thought it was just part of the coral when I put it in my tank but it started moving and looking more like a slug. My question is can anyone help identify it and...

Hello everyone! Okay so here's whats happening: I have a brittle star fish that hitchhiked on one of my rocks. Long story short its standing up, next to another one half its size. I read this could be spawning behavior and I just wanted anyone's opinion. Here's a picture (sorry for poor...

Found some things. I think I have tunicates and weird white encrusting things. Also two different red sps, about the size of a #2 pencil eraser. Birds nest?? Found a anenome looking guy. I think it's agressive. What is it? Im listing picks in order but some pics have two hitch hikers in them.

I dont know what this thing is and if its good or bad please someone tell me

ok, I hope the picture shows up ok. I got this blue mushroom about a week ago and I noticed it starting to lift. So I started looking at it closely to make sure nothing was wrong with it. The mushroom is only about 3/4 of an inch and there are these little what maybe look like aipatasias and...

Please help identify this anemone for me. It came with live rock, and it split already 2 times, so I have 3 of them now. They are fairly small, mouth disk is about 1/4 inch in diameter. They have bright green tentacle tips and the disk is kinda brownish. I am pretty sure its a nem because one of...

I got this coral as a hitchhiker on one of the rocks I got from my LFS. It started about 9 months ago as a barely visible 1/8 inch patch on the rock and now it has grown to about 1.5-2 inches. It seems to be spreading flatly over the rock and not making any branches or anything. Clearly it looks...
