Last week I set up a 90 gal. fish-only tank with live rock and live sand;protein skimmer; flourescent lighting 2 x 40W, 1 bulb is actinic. I am cycling now. I want to add starter inverts (e.g. cleaner crabs, snails, shrimp, etc.) this weekend followed by a few starter fish the following weekend when ammonia, etc. is zero. Any recommendations concerning specific types of starter inverts and fish, numbers, time to introduce and maintenance procedures, etc. would be greatly appreciated.
