One note - it would be best to keep only one pair in any tank together - UNLESS your tank is super-huge (i.e. 55gal or larger) and heavily planted. We have just bought three - and we THOUGHT we had got two females and one male, but it turns out that we got two males and one female. The males are fighting over the female and also over their territory. They head-butt each other - which is where they get their names - “Rams”. This is perfectly normal behavior for males in a tank with males - but it may be undesirable for the inexperienced aquarist - or for someone who just wants a peaceful pair.

Sexing these fish is very difficult at first - but with a few pointers you can do it. Do NOT rely on the tall dorsal fin spines to tell the males - this is unreliable. Instead - look for the smaller fish that may have a SLIGHT pink/rose colored sheen on their underbelly - these are FEMALES. Also - the females mostly swim around with their dorsal fins NOT raised or fanned-out. Apart from that - just about the only way to sex the species is to watch their behavior in the tank together - the males will swim around posturing with all of their fins fanned out, and the females will be (a little) more subdued.

They are great for community tanks - in fact our Dwarf. Gourami swims right into them or lands on top of them during feeding and they don’t bat an eyelid.

Good luck!!

I’m determined to get free swimming fry now lol. Getting microworms ready too.

Get these fish, very colorful and really stand out in a plant tank.
