Discus prefer a pH of 6.0, but I would recommend 6.5 so that you donât destroy your bacteria cycle. Temperatures should be around 27C-28C (80.6F - 82.4F). Discus canât tolerate ammonia, nitrite, or too much nitrate, so itâs a good idea to thoroughly cycle your tank before adding them as they are big fish.

Medical Definition of Lip. Lip: One of the two fleshy folds that surround the opening of the mouth. The upper lip is separated from the nose by the philtrum, the area that lies between the base of the nose and the pigmented edge (called the vermillion border or the carmine margin) of the upper lip. The upper and lower lips meet at the corners (angles) of the mouth, which are called the oral commissures.
