I breed my mollys in a 10 gallon tank and circulate them back to my 50 Gal. after the deed is done I do have my breeder tank a bit over stocked with three breeding pairs of mollys, Dalmatian, black, and sail fin. I keep the water very clean with a well working filter rated for 30 gallons. The tank has been established for a month or so. the fish are breeding and seemingly getting along just peachy, But they never stop and rest I have kept many other kinds of fish and never seen fish be so active. is this typical of mollys? Thanks!!
