i would have to agree with him, using a 10g, more space for water change and things a little off. Use a sponge filter or a power filter on slow gph with poly on intake. Feeding baby brine shrimp and move up to finly crumpled flakes. with daily water changes or at least every other day. If ur best use RO water for best sucess, 33cents/g at wal-mart, just 1g a day water change. With RO they will grow faster, be in better health too.
