Sandman,
I have used three different Foxface rabbit fish over the past seven or eight years to combat macroalage problems and never had any that were interested in “meat†The one I have now will not eat fresh shrimp or fish, only flake food and plant material. I am having trouble with Dictyota and have tried to introduce different macros to compete for nutrients but no luck. My present Foxface rabbit fish eats Botryocladia, Caulerpa peltata, racemosa, taxifolia like forms, Codium, and of course Dictyota.
The only negative I have with this fish is that it can quickly eat itself out of house and home while rapidly growing quite large and then it wants to be the only big fish in the tank. I am getting ready to take this one back to Inland Aquatics and trade for something else.
