I have redone my 10 gallon and removed the divider that separated my shrimp and betta. So far no shrimp deaths and the betta has blown his first bubble nest!!! But the betta is greedy, yesterday he ate 5 shrimp pellets and today he tried to eat an algae wafer. Normally he gets 4 small pellets or some daphnia. Can I put him off? Should I build something that is too small for a betta but fits shrimp just fine and hide the food in it?
