i just received a WWC Funny D this morning and put it right into quarantine. I have a heater, powerhead, HOB filter and the only light I have on hand is a cheap hardware store steel reflector with a plant bulb. I turned that on and 30 mins later the Zoa opened up and was open all day while the light was on. About 20 mins after I shut the light off it closed up again. Is that pretty common after shipping for it to close up without light?
