I'm planning to get a 55 gallon fish tank soon and I have 4 females and 1 male sword tail. I'm really tired of the batches of fry so I want to get a divider in my 55. Would it be alright to have the male alone in about 25 gallons of the tank and giving the 30 gallons to the rest of the fish. Would the fish have enough space? Would the male fish get lonely alone? I also plan on planting my tank pretty heavily so if the fish were together lots of the fry would survive.
