Hey I currently own a 20 gallon and a five gallon, I was wondering what fish could I put into my 75 which are pretty hardy, active and easily breed besides live bearers ( I dont have much time to breed due to school and work, but enjoy it) Right now I have baby fancy tails and a white cloud in the 5, then 2 plecos, two swords, a fancy, a dwarf groumai, a platy, an irradesent shark and two serpe tetras and 3 live plants what else can be added
