there were about 400 I think??? I think just by an estimated look that there are over 200 still. My tank is still full as ever. I have been doing small water changes with an airline tube about every three days. The liquid fry food clouds up the water a bit. I have some plant matter and gravel in the tank. I need to do a gravel vac, but I am unsure on how to do that with all the fry. I might have to wait or just move them. Any suggestions?
