I have a red devil cichlid that is 4 months old and 6 to 8 inches long. he has brown spots growing on his under belly it almost looks like algea. he is a big fish with a small domain he has to turn sideways to get in or out. he is in a tank with 6 other cichlids 3 over grown feeders and a picostamus sucker with no live plants or is exposed to sunlight
