Fish for 75 gallon?

That's easier said than done. First of all catching a fish in an established reef tank is near impossible. The fish will probably really stress out. Or you can wait until he floats to the top which by then should be too late. The best thing is to not put weak fish in a 75 gal reef tank. Save yourself the aggrevation Grant. You don't need it. When your thinking reef just stay away from any possible problems. We have enough to deal with.

 

There is an easier way and that is keeping cleaner shrimp as they will eat the ich off the tang or get a product that is reef friendly called Kick-Ich. I've used it and it worked without a fatality.
