Bev,
Wondering how your manderine is doing. I also have a manderine who is doing well in a 65 gal. mature tank 3 yrs. with lots of live rock, pods, and other microorganisms. Sounds like your fish are all compatible. I also have a blue chromis, 2 clarki, 3 pj cardinals and 1 scopus tang. The tang which is the biggest, is also the most dominant. Wondering if you ever got the flame angel. Depending on the amount of hiding places and size of your tank, the flame angel may get pushy and territorial, especially with the blue tang. It is good that you plan to add him last, as he will be less territorial that way.
I have noticed the clarki pushing the manderine out of "their spot". :rolleyes:
Does your manderine eat brine shrimp? I sometimes target feed him with a syringe, because the other fish will beat him to it. He also sucks it out of the power head foam prefilter which the others won't do. Some say that starfishes (especially choc. chip) will compete for the pods, so be careful not to add too many livestock that feed on pods, and your sweeties will stay fat and happy for a long time.
