my grow out tank is 3'x2'x2' with a 7 inch african arowana, 5 inch clown knife, 4 inch bichir, i want to breed some convicts to use as feeders. can i get a pair of 1 male and 1 female and breed them in my grow out tank and then move the fry to a 10 gallon? will this work or do i need the convicts in a tank by themselfs?
