They are GBR.
The first is male (Hiding).
His anal fin is the "tell".
None of the blue is in the spot and double or no spot is just water parameters IMO
I have seen males with blue on the edge/possibly in the spot.
Check out my photos as I have about 150-200 GBR(about 5-8 months old) now.
The ram prefers monogamy but are not "dedicated".
I have forced pairs and witnessed many "second couples" due to loss..
If they are are in a 10g with bloodfins you stand zero chance of breeding/raising success IMO
They need to be alone and fry separated to stand reasonable chance.
Just my opinion.
Many say otherwise?
