I was advised that for a reef setup the standard is 1" of fish per 5 gallons. Though i like the idea of 1"/2gal much better.usmc121581 said:The rule of thumb for saltwater is 1" per every 2 gallons of water. If you look at my signature, you can see that I have more fish then I am supposed to, but I have 4-5 different filtration methods on my setup.
Bottom line dan, is that it greatly depends on the total gallonage of your system. As I mentioned prior, if you upgrade to a wet/dry filter with a sump, or a Refugium, you also increase the total gallonage of your system, thus allowing you to increase the total number of fish.
I shouldnt have to tell you, though I have this odd feeling that I do, RESEARCH THE FISH BEFORE YOU BUY THEM. Make sure you are choosing fish that will not feed on your other fishes, corals, or inverts, and will survive in the conditions you plan to afford them.
