I have a 28g nano and currently have a true perc, onyx perc & bluespot jawfish. I planned to add a helfrichi firefish and a mystery wrasse as well but decided against the wrasse due to the size of the tank. Is 5 fish too many I keep going back and forth.
It would be my clownfish pair, bluespot jawfish, helfrichi firefish & a basslet of some sort.
