Most all sites have a certain amount of fish you have to buy,($ 75-100) and I don't need that many! Do you think a red empress would be happy in the set-up I have?Of course they would be in the 125g,all the fish are listed in my sig.The ph is 8.4,weekly water changes and hard water.Only thing I plan on changeing in the aquarium is getting rid of the pitus cats ,1 pleco and adding corys instead. thanks
