Added a 11" Uaru and rescued, so to speak, (2) 11" pink tail chalceus. Then chalceus were previously living in a 90g with GT's, perch, synspillum, lotus, etc. They were beaten pretty bad. Hoping to heal these two up with nothing but frequent water changes. may go to melafix if a problem occurs. They are, so far, really good with the discus. Strange mix, but it's working.
I like the random combination. Good looking tank. Nothing wrong with the tank mates since those discus are mostly old enough to have a strong immune system. Love the fact that you have a tall tank instead of a typical foot print.
Great looking tank... nice filtration you got as well.
How long exactly have you been doing water changes like that? I've always done weekly 50%, but have wanted to do 40-70% 2-3x a week for my dempseys in my 55g (as they are really starting to grow) but seen a few articles online mention frequent water changes would stress out the fish.
