i will be adding a skimmer to the tank soon (after i get my funds). I just set the tank up with water from a tank i tore down over the weekend, and i bought my seahorses on MLK day. keep in mind, the tank had been running since friday and nothing had changed as it was basically the same equipment, media, pads for bacteria, and rock and sand that was in my 15 tall. I aid $100 for a pair of tank raised erectus, but they are all black currently as i really dont have any color in the tank for them. i do have hitching posts out of artificial coral and some dead gorgorieans. this week i plan to add lot of mmushrooms (like watermellons and redish-purples t the tank for a uniique color combo. i am wondering however, can a hammer coral be placed into a tank with seahorses? if not thats ok, but if so im going to add it first thing tomorrow
