Im looking to start one. My cousin has one and i love it. He said he spends 10-30 minutes on it each day. His friend gave him a fish that had a disease and he didnt know it so when he put it in his tank it killed like $500 worth of fish and coral. The only reason why i may not get one is only because its soooo expensive. Oh ya and there are aquarium message boards just like this one. Fengzi, tell me a little bit more about your tank and the stuff you had to do on a daily basis to keep the fish healthy. Thanks
