I have a nano tank. I have 1 pajama cardinal, (for a few reasons including I was in my local fish store and they had this single little fish in a huge tank by itself because the day before someone bought it’s buddies and they had no idea if or when the would get more) it is the smallest in my tank. I know they are best in pairs or more. Some question:
1 if I can find another small one, should I add it or will it not be happy with the new one?
2 if not, will my present pj cardinal like and hang out with a firefish? (Or do they just like to hang with their own)
3 does the sex matter (if I find another small one) and if so how do I tell what I have?
4 if I added a bangai cardinal, with it and my pj hang together like 2 pjs might?
Thank you
