Ok well I have a very deep sand bed two large live rocks one shroom head cuz it came on the rock and I have not managed to kill it in a year

there are some crabs and two emeralds that hide inside one of the rocks that is actually sort of buried in the sand..some of them are supposed to go back to the display but just have not caught em yet

then there is an anemone baby whose foot is the size of a quarter and my mean ocellaris who can't get along in my display

i have no skimmer because i gave my fission to my friend ...we tried the more direct hookup recommended on their site...and go figure it works fine for her...on my 20 trash

I do water changes and there is an Aqua Clear 30 power head pointed at the glass that gives almost a tornado action around the tank and a small ten gallon filter with a 30 gallon motor that pulls the water through carbon and a few layers of floss
