are grouper fish reef safe?

One of my friends just asked me this question and I really wasnt sure, she has 2 grouper fish(im not sure what kind the are) in her 100 gallon tank and she wants to start puting corals in the tank, so would there a problem with doing so?

I don't think they will hurt corals, but all smaller fish and inverts will become food. 2 groupers in a 100 gallon is kind of pushing it as well.

As far as corals go, they will be fine. However with two groupers in a 100 gallon I would be concerned about the water quality -- they get big and produce a lot of waste.

yeah her water quality is horrible i asked her when the last time she did a water change and she told me "oh we are putting fresh water in the tank all the time" and didnt quite get the concept of changing out water, Doh! so I'm going there tonight and going to preach her the evils of not doing water changes

Good for you.

The last thing she should do is add corals to that tank.
