Ok, so this is my first post on here, so a little about my setup first. I have a 46G tank, about 5 inches of sand at the bottom, about 50lbs of live rock. I use a CPR bakpak for filtration and a 9W Submariner UV Sterilizer, as well as an extra powerhead for added current/surface agitation. Current inhabitants are two Clowns, Flame Angle, Neon Spot Wrasse, Red Coris Wrasse, 2 Fiji Blue Devils, one Pacific Blue Tang, one Skunk shrimp one emerald crab, one Haitian pink tip anemone and three (used to be one until a few weeks ago) bubble tip anemones, as well as a few snails. The tank has been setup for about 3 years, so it's well established, so I hope.
Now to my problem, if one even exists. My fish usually get fed three times a day, Mysis shrimp in the morning, and then I have a feeder that feeds them twice (once early afternoon and once in the evening, about 45 minutes before they go to sleep. Over the past week or so, my Tang has started to splash water all over the place with his tail, right in the corner where the food usually comes in. Is he just hungry and I need to reduce the amount of food, but increase it from twice a day to three? Or is he just being a brat and wanting to play? He seems fine, still swims around all happy, but I don't like having to dry up my floor every day, plus of course I don't want the splashing water to damage anything else.
Any ideas?
