Last year in Feb. I set up a 45 gallon tall with about 60 lbs of live rock, 3 lil power heads and a 150w metal halide...Now here's what it looks like a year later, with no water changes, supplements (except for the tap water I top up with). I've added some soft coral frags, small snails and serpent stars. All going good EXCEPT for the several thousand flatworms that cover everything, and dozen the benthic comb jellies (ctenophores) that seem to have colonized my biggest leather (although they don't hurt it, just "fish" around the tank with their tentacles).
