What the heck?????

[3fsh]

What the heck are these? Anyone have a clue what they are? They've been in my tank for a couple of months now and they're spreading like wildfire. They almost act like a jellyfish... if you touch them they pull their little tentacles back into their body. If anyone has the slightest clue what they are, please let me know! I hope they won't hurt my fish. Here is a pic:

They are only a couple of millemeters long... sorry for the fuzzy pic!

I'm not sure, but it looks like it might be hydra. Google it and see. If it is, it can be a problem for small fish. Gouramis (pearls, blues, golds and opalines) will eat hydra. HTH!

Yep, looks like hydra - let me add moonlight gouramies to that list Just buy yourself one of the magnificent pearl gouramies and he'll rid your tank of those pesky little critters once and for all! Never seen a single one in my tanks and have pearl gouramies (or other gouramies) in all of them.

They act more like coral pollyps IMO though...

I really woundlt get rid of them...they filter your tanks! ahh...natural filtrarion

Yep, they are definitely hydra! So, what do I do? Get rid of them with a gourami or leave them? It's a 10g tank that I'm planning on putting guppies and some ottos in. Will they harm these fish? I don't mind if they eat the fry produced by the guppies. I don't have any spare tanks to raise fry in anyway.

I don't think they're realy a problem. Leave them and if you notice problems you can put a dwarf gourami in there and let it eat them up for you
