Are they all males

[Bradyfam]

I know it hard to see but do you guys think these are all males. They are endlers

Indeed males (all 4 shown).
These are not pure endlers. They appear to be hybrids, at least partly 'snakeskin guppies', possibly crossed with endlers and who knows which other varieties.
Nice fish!
