So the male dempsey passed away after the jag got to him more. so i removed the fish and the jag. I did another water changes( 15 gallons) and now there is 1 parrot, 1 firemouth both of which are very healthy. The Female dempsey I left in there since she is smaller and less agressive. Im gonna do another Wc on sunday. And next week a wc on saturday then purchase i think a severum or some giant danios probably like 7-8. does that sound good or should i continue the wc through next week?
