Recently took home a pajama cardinal because I think they look pretty cool, However my girl likes the bangai's the most to the point where shes is bugging me about getting one and compatibility between the two. I have done a good amount of research and haven't found any info saying they can not go together and I have seen other cardinalfish listed as compatible with pj cardinals. I do know that two pjs will beat each other up unless they are housed one male and one female or in a large group in which they have a strict hierarchy. This is what I read im sure other have had different experiences but I would just like to know if anyone has had pjs and bangais housed together safely.
