I’m currently building a 10 gallon nano and need live stock ideas. I don’t want clownfish since I already have a pair in my Biocube. I was thinking a trio of cardinal fish (Pajama/banggai) but what would happen if two of them pair up. Would they pick on the third. What are some other good livestock ideas you could recommend. Also I’m going lidless so can’t put in any fish prone to jumping. Let me know what you think. Thanks!
