Fins is what I was looking at. The larger 'male' one definitely has a point at the tip of his dorsal and all the other fins are diamond type shapes. The smaller 'female' has much more rounded fins so I'm pretty confident it's a pair. The female does seem to be getting a little rounder in the belly too. When the quarantine tank has done it's quarantining thing I'll probably move this pair into that and see what happens (thinking they may be ok with the warm temps a zebra plec may need).Gingerlove05 wrote: ↑Mon Feb 03, 2020 20:53 pm Generally colouring up is a sign of happy fish
Looking at the fins they do look male and female from what i can see, but rams are hard to sex without being the electric blues
On a plus note if they do breed and get it right (it might take a few goes) for a while they will look after the young, protecting them and herding them around the tank to various feeding areas
The german blue rams are a bit more hard to sex. They're still smaller, but I've seen similar size in pet shops and they have the obvious pink belly. Mine don't seem to have that, but one does has black edges on it's pelvic fins which I believe means it's a girl? Hard to double check as they hide a lot and get chased by the blues if they break cover and start showing their finnage.
If I was to add more rams to main tank, would I be best just adding females to reduce aggression or once a pair is formed, will they be aggressive to all other rams?
) in females if they’re in the right mood, its around by the anal fin
