Hello
I just got a bloodred RedDevil, its around 4-4.5". I want to know beside males get a hump and females dont or have smaller humps, is there any other way to sex it?
not to sure how to vent.yes you could do it at tha size but im really not sure what to look for. try searching the site for ventinh. im sure youll find something
To vent you need to look at the area around the naughty bit. If its U shaped its female. If it looks V shaped its a male. The bad part is you really have to take the fish out of the tank and flip it over....
