As long as they dont harm my fry...live and let live. Im cleaning my tank this weekend anyway so...Thanks Sensei OFL for once again imparting and sharing your knowledge with us.

Thats about right.....the ones in my tanks vary from pin head to larger and I am sure lots more that I can't see....

One of these things, whole, is smaller than a pinhead.

Usually they are smaller than new born Betta fry.

Out of curiosity what is the size of hydra? One like you mentioned: that can kill fry and sting...

Very true..it would be hard to get a pic, however, hydra generally are not harmful to adult Betta-they can kill fry and even give you a tiny sting-doesn't hurt too bad but it can startle you a bit...at least it does me.....

I can try and hopefully it will come out because these things are faint. If it is hydra, hopefully it wont harm my fry.

Thats sounds like hydra...can you make a thread on the main board and post some pics...be sure and VM me and I will take a look...

This is the great unknown white algae I swear. I cant find info on the net on it or anything. Im pretty sure its not hydra because I see no tentacles. When it sways it looks like an umbrella when its turned inside out by a gust of wind.

Are you sure its not hydra...that is the only thing I can think of....Most critters in our tanks are harmless....
