Take a look after the lights have been out for 3 or 4 hours, your jaw
will drop. I went through a thunder storm power outage here in Dallas
last night and was checking the fish about 3 AM and there were many
thousands in my 110.

I have so many of these things they form themselves into little rafts &
float around the top of the water. They are a plague and I wish I'd never
laid eyes on them. My clown loaches don't touch them. Other than tearing
everything down & starting over, how do I get rid of them... or at least
control their population?
