hi all, i have a small group of five of these little guys, all between one and a half and three inches. lately i have definitely seen a couple of them fighting, but also two in particular who are always kind of swimming slowly around eachother, putting their fins on display, that sort of stuff. a lot of time they do this nose to tail thing as well...are they thinking about doing it!?? lol. i'm really hoping these guys and gals will breed for me...anybody have any experience with them? things to look for in breeding behavior? any advice would be appreciated as always
