Yellow Tang- fin "rot" from eating too much meat???

[NYFrank]

I have been reading some threads on nutrition. 2 of my 3 yellow tangs have some fin ââ"šÂ¬Ã…"œrotââ"šÂ¬Ã‚ it almost looks like another fish has nipped them at the ends but it also appears as holes just above the body on the fin between the spines. I feed them a wide variety of frozen, flake and pellet. Squid, clams, brine, plankton, mysis shrimp, formula 1 and 2, dried green and brown algae. Lately I have noticed the tangs eating a lot of the meaty foods. They continue to eat well and graze off tank algae all day. This started about 3 days ago. Any ideas as to what this could be.
Water par are good, nothing went out of the norm.

I've never heard of a tang having fin rot due to excess meat in its diet. I'd assume there's something else causing this. Maybe post this in the Fish Disease forum to get better answers.

Tangs are herbivores and will be malnourished if you don't feed them a diet high in veggies. Since they are garbage eaters and will eat almost anything you throw in the tank, you need to make sure they aren't just eating "meat" as you will start to have problems like what you are seeing now.

Yes that is what I have been seeing and read- They eat the meaty stuff first and than after all is gone will eat veggies. I have cut back the meat and been putting in dried algae and formula 2. how long before I begin to see a difference in the fins?
