Is there any thing that can be done to regain the zooxanthellae in a BTA?
Give adequate lighting. Other than that, there is evidence that certain corals and anemones can absorb zooxanthellae from the water column, so if your specimen is totally devoid of zooxanthellae, perhaps having it in a tank with other conspecifics may help.
