i have a question pertaining to releasing fish to the wild. so if i have a 135 gallon, its completely dry. i filled it with water and caught 2 texas cichlids about 15 Mexican tetras and 1 tilapia. all caught from a stream close to me. if i were to bread the fish for a generation or two could i then later release the parents or what not back to there original water? i use no chemicals, the only thing i put in the tank that they would not naturally come by in there stream is the fish food. i don't want to do anything harmful, i would however like to be able to put back what i took (or at least the equivalent number of what i took)
