Thanks.

I guess the solution is to add some fish that will eat those things. I had some galaxies in there, but they jumped out (an expensive fish to find dead on the floor)... the challenge will be to find something that will eat the bugs but not the baby shrimp and that is small enough to be happy in there...

Anyone familiar with Brachygobius aggregatus (Schooling Bumblebee Goby)? I am tempted to give them a try because of their size...
