The most beautiful freshwater fish is definitely Discus. That is why he is also called the king of freshwater aquariums. I feed them food Tetra Discus Colour and are beautifully coloredInclude pics if you have them!
This is my favorite so far. (Jewel) I recently had a white top afra male that was gorgeous!!! Buuuut I could not find a female so I sold him at the pet store. Funny thing....once the pet store took him, they placed him in a tank with big cichlids and now his color is all gone and hes a lead grey color. (No wonder he is not selling he he he)
