Daphnia are People Too.
I agree that angels in even numbers are best. In a 55 gallon, you could keep 4. In a 40 gallon, you could keep 2. I keep mine in a community that includes bamboo shrimp and there is no issue since the shrimp are so big. If you want any other tankmates (tetra school, corys, algae eaters), add them first and the angels last. avoid fish under 2 inches because the angels can swallow them. If you have 4, put tall plnats/decor in the middle to help the angels set up natural territories on either side of the tank. Tell your dad to watch for aggression and nipped fins. Sometimes, you can do everything right, but just have a jerky angel.
