ok I have a Jack Dempsey around the 3 inch mark or so, currently in a 30 Gallon (55 is being desnailed at the moment) and ive had this problem even in the 55, he shares a tank with 1 firemouth who is smaller, and a couple of Raphael Catfish, a pleco and thats about it, he will get a pale yellow color, then sometimes will get stripes, then will sometimes turn brownish, the PH is around 7-7.2, i do water changes every week (25%) and im not sure why he is always changing colors, does anyone know?
