My family has a 500 U.S. gal. pond in the front. I am the only one with fish tanks. Winter is around the corner and the tempature of the water is at 65 degrees F. I took the 5 Plecos out as I do every winter and they are varying sizes. The tank they're in is a 29 U.S. Gallon and I want to know if a 9" incher, 3x 5" inchers, and a 4" incher missing a Pectoral fin can live together over winter? I can't put some in the other 29 cause of my Swordplants and I don't wan't their aggression to be inflicted on my 2x 1" Albino Bristlenoses and my 4" Senegal Bichir. Also it might crowd that tank and I am trying to get my HRP's to breed and don't need them to eat the eggs. I am sure they can protect eggs from 1" bristles but not those armored beasts. Help me!!!!
