I have a sand bed. really any fish is ok. We haven't kept a salt tank in about 28 yrs. Woke up one morning and evrything was dead. :( So we gave up fish and started raising kids (2 boys). :wacko I think the fish may have been eaisier to raise. I am just looking for something that is cool to watch. With 3yr old twins visiting they always run to the tank and look for Nemo and Marlin. :P Need something else that they would like.
