Trevor - 2013-05-14 I have had my blue spotted grouper for about 3 years now and he is the definitely the hardiest fish i've ever witnessed. My fishes face also turned white! That started as a spot about a year ago and now its across his WHOLE FACE! He is a perfectly healthy fish, hungriest ive ever owned. Your comment actually brought me to this site because I was looking up why that would have happened. Is that normal??? Clarice Brough - 2013-05-14 That is a curious phenomenon that apparently it does happen, and doesn't seem to be a problem for the fish. Reply

glmory - 2008-11-27 I had one of these in a 100 gallon tank for about two years. It is a great fish, but don't keep it with anything small. It will eat any Damsels in the tank within days. It ultimately died when it got put in a tank with a Tesselata eel which is the far larger and more aggressive species. It managed to stay a while with this eel, but was eaten in the end. Reply

Chris Logan - 2006-09-12 I have had one of these for the past two years and it is awesome. I feed him Formula One which really brings out his colors. When I bring his food to the tank he comes right up to the top like he's begging. This is the hardiest fish I have ever owned. About a year ago I had a bad ammonia spike and he was the only fish to survive. These are great fish! Reply
