    Hi,
    I hope this is in the right forum.
    I have a query and unfortunately i cant take a photo coz what i need to identify is too far back and too small to take a pic.
    Ill try describe as best as possible.


    Its about 5mm big. Its white and has slight "hairs"/tentacles. The best way to describe it is it looks like a tiny cactus. A round one. It has fine hair all around it. and what looks like a "flower" on the top.
    One week i was looking in the tank and found one, the next week i saw 4 of them.
    Can anyone help?

    hmmmm tough one from the description. It sounds like a type of nudibranch to me, but its small for a nudi and they typically dont multiply in a tank that fast. also with them mutilying (taking the assumption that they wernt there before and you missed them) it would denote that they have a food source and can sustian themselves in an aquarium, which again is NOT like a nudibranch typically.

    i do wonder about the hairs and without seeing the thing live i am not sure if the hairs are part of a protection or used as filter feeding, knowing which will help greatly in its ID.

    its possible its a small worm (not a flat worm as you describe them as round). A pic may help though.

    what colour is the 'flower' onto of them, is it also white? can you tell anything about feeding?

    @shiya you have any ideas?

    Hey Crispin, I think Regis may be right. I did a google search for sponges and found a pic that looks similar to them. The little "flower" on top is white.
    I have been watching the tank since it was filled and have been searching for algae growth and have been real attentive for new things and these things grew pretty fast. I dont think its a worm as they havent moved. They have been in the same place the past week or so.
    The tentacles are tiny. May not even be tentacles.

    i agree 459b, it looks like a sponge and sounds like a sea-squirt or turnicate of some sort
    i have plenty in the dark low flow areas of my tank

    hang on....do they move or are they static in one place? they look like tunicates of some form to me.

    sorry i thought they were mobile and was thinking along those lines before you posted the blurry pics:)
