With the advice you have given me, the only problems I foresee is the feeding 2 to 3 times a day. I would be able to feed in the morning before work and again around 4:30pm and then again before bed, would this be good enough? The temperature of 72 to 74 might be a problem, I will have to just set the tank up and then play with it till I can keep the temputures at that level.Keeping the tank at 72 to 74 degrees may mean keeping the seahorse tank seperate from my main tanks sump, meaning, set up the seahorse tank with its own sump. What kind of lights would be best for the tank, T5s, a refugeuim light? Sounds to me like a good seahorse tank would almost be like a refugeium (sp) tank. As far as tank mates that i want for the seahorses, clean up crew and thats about it, I want the seahorses to thrive before I think about anything else. I would like to put some zoas and polyps in the tank, but that depends on the light you recommend for the tank, can't heat the water up to much. Temputure is something I will have to just play with till I get it right before getting the seahorses. As far as the power head for the tank goes, would the return line from the sump provide enough water movement for the tank or is something else needed? As far as buying Seahorses, I am aways from that point, but when the time comes I will post again for ya'lls recommendations.
