Hi, I was just wondering if anyone can tell me about the activity level of a Giraffe Catfish. I just bought a 5 inch juvinille Giraffe yesterday and he doesn't move around very much, unless of course there is food to be eaten and then he's all over the place. I was just wondering if this is normal behavior or if maybe he's behaving differently due to possibly different water conditions of the pet store and then my home.
