the splitting of the anemone is a bad sign. they usually do this because of stress.
you need about double the live rock you have for that size tank. you will need to cure that rock in a separate container, now that the main tank is loaded with livestock.
also, i think your snowflake eel is going to swallow up the damsels and clownfish eventually.
also, 4 x 54 watt t-5 lamps is not going to be enough to keep your sps
colorful, and maybe not even the anemone. what are the dimensions of this tank? how deep top to bottom?
