Yes, Pat I did. Here is what they have to say about them. I have had the copperband butterflyfish and getting them to eat other food other than the aiptasia was what I had problems with and hear that from many.
The Tahitian butterflyfish (Chaetodon trichrous), sometimes simply called the Tahiti butterflyfish, is a fantastic fish when it comes to controlling aiptasia in a saltwater aquarium. Best of all, it is far hardier than other fishes commonly known to eat aiptasia (e.g., copperband butterflyfish). When added to a peaceful community tank of at least 50 gallons, this attractive fish will target any pest anemones in the aquarium, and, once the aiptasia is gone, it will readily accept a captive diet.
Originating from the eastern Pacific around the Society Islands, Tahiti, and the Tuamoto Islands, the Tahitian butterflyfish may grow to about 12 cm. It is considered a reef-compatible species by most aquarist, although it has been known to nip at some polyps in a few isolated situations. Keeping this fish well fed may go a long way toward avoiding any problems in a reef tank. Offer it meaty bits of table seafood, along with foods commercially prepared for ominvores and carnivores.
"Using a vitamin supplement, along with frequent offerings of meaty marine flesh, will help the Tahitian butterfly retain its colors," suggests Mark Martin, director of marine ornamental research at Blue Zoo. "So once the aiptasia is gone, you will have a beautiful fish to add color and interest to your aquarium."
