Hehe, just had to do that. I've been reading up a lot about tanks for kids. They are the reason I got myself into this business of aquarium keeping. I promised them if they got good report cards they could have a fish tank. I did not know what I was getting into. A lot of sites say clams, crayfish, snails and crabs (all freshwater) are really enjoyable for kids. I kind of ran this by my kids and they really thought it would be coold to have a tank with as many different things as we could, including fish. My problems is that I'm not too sure if these other creatures are compatible with any fish. And if they are what fish would be safe in the tank with them? I couldn't find a lot of information about it and thought someone here could give me some insight. I really think it would be neat for them to be exposed to different creatures and be able to observe thier habits too. What does everyone think?
