does anyone have any suggestions on breeding snakeheads? someone i know has 2 red snakeheads they are trying to breed with no luck... they are in a monster tank about 300 gallons or more bow front tank.. they have an undergravel filter with 3 or more powerheads on top. they have a big cave to hide in and some plants floating around... water quality is tip top shape and cleaned daily if needed. any info will be appreciated and passed on to them.. thank you.
