Ok, how big do these fish need to be in order to spawn? 2'', 3'', 4''? Just curious, because i wanna spawn some fishes. My tank is getting boring and I need to spice it up a bit, plus my perc is looking sad and lonely. Oh ya and, how much bigger does the female- to-be clown have to be than the male? Twice the size? a little bigger? same size, More aggressive?
