Thanks everyone! I have heard reading previous posts that they need to be fed fequently. They currently reside in my 90 gallon, but I do not ever feed them more than once every other day and they are doing awesome. I have had them for nearly 2 years now without a problem. They are fat and healthy.
I think that not keeping them is a good idea since they are my favorite fish, and would hate to see them have problems because of the size of their tank. My question for future reference is, are people over feeding them? I have heard that a lot of people have a really hard time keeping them alive.
