The Cichlid room companion is usually good ... slow when new changes in genus come about, but that is normal. Just becuase one scientist says fish A really should be in genus C instead of D, there is normally a good while while other scientists talk, discuss, argue, lie, threaten, and finally decided if it should be moved to C or stay in D. That process has been known to take years. For example, the new central american sifter genus isn't listed yet, but it's a brand new genus that hasn't been fully accepted yet.
Some people still don't acknowledge that Cichlasoma and Aequindens have been split up 25+ years later!
