What water conditions do angelfish like?
Angelfish prefer slightly acidic water. While keeping them, keep the pH between 6.2 and 6.8 to avoid 'black death disease.' Although they are demanding about water, they also dislike frequent water changes because they like still water; prolonged strong currents weaken them. A circulation filter helps slow water degradation.
