[Myteemouse]

hydroids thats the name for them..
I knew I read that befor just couldn't remember..

Yep, like adam said, first one bad, second not a biggie, they generally die out quickly.

In total agreement. Bad Nudibranch and Hydroid. Hydroids can be bad if you get a huge population of them. They seem to be part of newer tanks for me...lol. I get them a few months after a tank has been set up and they die off. I've never worried about them.
