i went to my lfs today to get some food for my fish and and i ask if they had green severums they didn't then i asked a friend of mine who works there if he could order one he said sure so ill be getting one soon : )
red-headed severums are awesome!!!! do a google search and you'll see what i mean. also, IMO the most laid back cichlid are definately discus. they school too, so they look awesome in a show tank. the only downside is lack of personality
