i really like this colourful lively little fish, but am not too keen on breeding, would it be fair on them to have males only

I would not try to keep these fish with a betta.

I have never had endlers, so would have to refer your question to CWC or Dino, or other more experienced.

We've got a tank full of male endlers and they seem happy. But they would need their own tank. They're colorful and hyper and wouldn't be good for a betta.

A male only tank with lots of plants would be awesome.
