My boyfriend wants to start breeding fish again he has two-20 gallons two-30 gallons one-40 gallon and three-50 gallon. Most of those are from when he was breeding fish before. Its been around 4-5 years since he last bred anything so i'm thinking it should be something easy. It'll aslo be feeder fish for the gar he's going to get in the next year and he wants to have the fish astablished and breeding for awhile before he gets the gar. the gar will be in a 500 gallon he has.
