I have a group of (5) 3 inchers some a little smaller trying to get an idea of who is who is it possible to vent at this size? I have vented and posted pics before but it was always larger fish. Any help is appreciated
It is possible to vent at a smaller size, but you need to be really good at it first & its still not very accurate. I've ordered a group of juvies from Rapps before trying to grow out a really nice male - requested all males from him and at around 2in, he was better than 75% accurate. I was impressed.
