I'm researching Yellow Labs for my 46g, and I just wanted your opinion. http://http://www.aquariumlife.net/profiles/african-cichlids/electric-yellow-lab/100004.asp That link says maximum size is 55g. Is that too much of a difference? And it doesn't say much about the diet. Anyone know? I'm really looking into this, I know, but I just want to be sure about this. Thanks!
