My brevis that I have had for the last three years have finally produced fry for the first time. It looks like there are multiple groups of fry. As a rough count there are probably 60 or so of them. My problem is that I have been putting off cleaning the tank (other than water changes) for a little while and the tank seems to be getting out of control. I would like to sift the gravel, but I don't want to suck up or injure any of the fry. Do I have to wait until they are big enough or will I have to make new accommodations by investing in a grow-out tank? Thanks for the help.
