5 days ago I had 30+ brichardi fry in a species only tank.Today I count only 3. My best guess is they weren't getting food and starved. Is this a possibility? How can I asure the next generation gets enough to eat. This is a tall 55g tank and by the time the flake gets down there the other guys eat it. I tried to sink alge waffers down to their pit,but they didn't seem interested in it. Any and all suggestions will be appreciated.
