How long did you have them before they spit out their babies ?I got a few at petco and now a pair is breeding! This is some of their brood.
hearing for years they are easy to breed , I’ve tried numerous times but similar to chromis they always end with only 1 shortly after acclimating .
The last time I bought a pair that was swimming together in the lfs.
Added them to my system and they both went to separate ends of the tank .
