My boyfriend wants to start breeding fish again (used to breed guppies as food for some of his fish until those fish died then he stoped breeding them) and wants something easy but doesn't want guppies and also wants something that doesn't need a huge amount of room can fit in a 30 gal or smaller. He has three 30 gal, one 20 gal, and five 10 gal tanks with filters, heaters, all that stuff.
