lifen Posted March 30, 2013 Share Posted March 30, 2013 The black spot is situated on one of his velvet blue bands. Its a pretty big spot, goes the whole width of the band and about 0.5 cm in length. He has enough algae to graze from. Water changes every week, although it has to be said that the last 3 WC's happened with old water, I still had stored. Could this be the problem? 1 Quote Link to comment
