BTW, GaryP's are the fattest healthiest CBB's I've seen. And like I said, there is always an experienced reefer with a lot in equipment that can provide an example of total gallons with all the refugium, sump, skimmer, overflow and tank thats less in gallons. But more is better in this case because of the total weight per ounze of body weight in food they need to consume. Its high protein food too, such as mussels, clams, mysis, ocean plankton, sandbed worms. It takes a serious system and water changes for that to work in the long run.

Also, the CBB, once tamed and acclimated to life in the tank and frozen food will not know its not a tang. It will chase food and compete with all the others just the same, current or no current. Mine are pigs and are the first fish to come to my hand for food. The others all hang back. In case someone doesn't want to tame one, please leave it in the ocean then. It has to be tamed to live a long healthy happy life in your reef. Things are different in there as is the availablility and time of availability of the food.

Yes, they will get a few pods and bristle worms now and then from the rocks and sand but not enough to sustain them in your tank. You can tell when they get a Gammarus shrimp cause its hard to crunch (some of those even get away after they are caught) and a live little bristle worm will make them shake their snout like they just ate a good hot pepper and can't wait for another one. But that all depends on them recovering from handling and shipping first and starting to eat. They can't eat that or smaller aiptasia until their snout is healed from handling, stress and salinity shock. As always, best as one of the first fish in the tank with tangs being the last addition to the tank. Some where along the line this seems to have been forgotten about in the stages of planning the reef it seems?
