I remeber when i first started keeping reef tanks how difficult it was to maintain a healthy tank. It just seems to me that it is hard enough in this hobby to maintain one tank in the begining with out throwing in medicated dips and another tank to watch. in the begining I think hobbyist should start with hardy fish that can with stand there mistakes and tryto master just one tank. If they can do that and feel that a q. tank is a good idea them they should get one. throwing a 1000 things at a new hobbyist will drive them out of the hobby.
