Is it possible to have a lemon jake or eureka in a 55gallon tank or should I stay with the smaller 5" variety peacocks. Also with the tank over filtered, whats everyone's thoughts on how many fish in an all male tank? I know everyone says 1" per gallon... Thanks for any input. I've been looking and really want to get a blue regal, a German red/or eureka, a lemon jake/benga, are there any bright orange peacocks? I'm trying to put together a bright colorful tank. Any suggestions?
