I’ve attempted to keep this species on different occasions and they all refused to show polyp extension no matter what I did. The best I could get was to have their polyps bubbling just under the corallite but never fully out. I’ve tried feeding them at different times of day, low flow, high flow, etc. Some did consume the food and some refused everything offered and they all slowly wasted away. Those that ate had non-sticking tentacles and I had to turn off all the pumps and laid the food direct over their mouths for them to eat. I’ve had great success with T. megacorallita and T. faulkneri but never with D. arbuscula. What should I do?
