i like ur scats alot. how about any pics of your moray? i've got one, seems not too many others do. also, my brackish tank had gravel and i changed over to sand, i like it ALOT better. the moray digs in it and makes holes around his rock so he can peek from under it, and my gobies seem to like it more than gravel also. i use argonite but a suggestion would be using some black sand, one of my LFS's have that for their brackish tanks and it brings out the color in the fish really well.
