Following advice from a few websites and because I've fallen in love with Pearl Gouramis, I increased my stock to 4. The last two didn't have a lot of color at the LFS but now that they are settling in, 3 very clearly have orange throats and one does not. According to this and other sites, that means I have 3 males and one female. So far everyone is content, so I'm wondering if I should try to exchange one. If so, do I swap a male for a female so as to have 2 of each? Or do I go with all males? Keeper of fish 2 years Tank: Freshwater no live plants 46g.
