Hydra

A few of these turned up in my office tank today. Hydra a tiny little predator, but harmless to any snail or fish. they might be risky with shrimp. But any tank with fish in it has a built in 'hydra-elimination' force. :)

New snail eggs

I am going to start this post with my latest eggs. The best prediction I have received online is that these are from a pond snail, a.k.a. Physa. I think otherwise, but we shall see.

Okay, I have to concede that they were Physa (a.k.a. pond or bladder snail) eggs [see left]. Physas are quite cute little snails but on a 10 gallon they are far too likely to over-populate and become a problem--so they had to go.

I seem to have a few survivors, including this rather interesting color variant.
