I have been running a Nuvo Marine 38 gallon with Seahorses in it for almost a year. No babies yet, however I connected 2 valves to the water pump, to slow the return into the tank. Seahorses were hiding way to much. Fixed that problem. I have hung two HOBs on the back of the tank, which allows me a turnover rate that is excellent, without disturbing the Seahorses too much. One of the HOBs is a aquatop including a UV light. Added chem pure and some live rock, as well as ceramic rings. The other HOB contains more filter media and another chempure as well. I have a nuvo marine skimmer, which pulls alot of icky stuff out of the water. I keep my tank at a temp between 70 and 72. My chiller is set at 73. I preform a weekly water change. Is this over the top? I do not really think so. I invested a good some of cash, as I know most enthusiast do. The enjoyment and mystery of keeping seahorse is worth it. Please preserve what the oceans have. Remember, captive bred is better.
