The tank is a 20L and ammonia, nitrite, nitrate are all 0. pH is 7.8 and SG
is 1.023. I only have the clownfish and a damsel right now since my **** damsel kills anything else I put in there. The fish that used to keep him in line died over the past couple of years. I've had the anemone for a couple of months now and he does keep his foot out of light and stretch into the light most of the time. He also seems to favor the acintic side of the spectrum leaning towards the back of the tank (also frustrating). The hanging upside down and closing while the light is on is what bothers me. Is that normal?
