Need help identifing creature on my glass.

[jasno999]

I found a few of these on my glass. At first I thought it was algae. However it was a little bit biger than a strand of hair algae and as I watched it I noticed that it actually moved like a snail almost on the glass.

They are very small.

Cany somebody make suggestions as to what they are. ARe they good or bad? These are the best photos I could get cause it was so small.

Resembles a pest nudi.Very hard to tell from the pics.Are there any corals in the tank ?

Looks like a nudibranch sort of. Try to get some better pics. Are you sure it moves?

[jasno999]

I am positive that it moves. There are thre on my glass right now. THat is the best picture I can get cause it is so small the camera can't focus well on it.

What is a pest nudi? I do have coral in my tank. Bubble coral, mushroom and sand polyup

ARe these bad for my tank?

[jasno999]

Crap. I am in a bind. I also noticed to aiptasia anemones in my tank. One was on rubble rock so I jsut removed the entire rock fro mthe tank. Theo other I tried to remove with tweezers but not sure if I go all of it.

Now I am wondering if I should just leave these things that appear to be Berghia Nudibranch or some sort of Nudibranch... I can't really remove them anyway. If I see them on the glass I could but you know there would be more elsewhere in the tank.

I have a bubble coral i nthe tank, mushrooms and sand polyups. THe sand polyups are not doing great as they have been closed for several days since I moved them to a new section of the tank.

anybody else that can help me out?


LAst night I actually pulled a chair up to my tank to sit and watch it for an extended period. I always watch it but never for that long at that close a distance. I noticed so many new and interestign things by doing that.

That is how I saw all of these creatures. I think I so a coepod running on the rock. I say these smal lthings on the glass and the Aiptasia. I also saw a pretty large work in the back of the tank. This thing was rather large and was hiding or living in my macro algae. Looked liek he was coming out to try and find a place in the rock structure to hidie or go.

I am not positive of what kind of worm it was. He was too far in the tank to get a godo picture. I am hoping that he is a bristleworm and nto a fireworm. He did sort of look like one of the legs on my brittle star but he had a bit of a reddish color to him.

Really amazign stuff but at the same time scary stuff causeI am worried I may have unwanted guests.
