I have a red sea max 130d both power heads run all the time and also a koralia running at random. at night, the two stock powerheads plus a vortech 10 in reefcrest mode the horses are better swimmers than one thinks as long as there is rock and caulpera plants to hang onto for hunting and hitching,they can handle more flow than one thinks. You will find that the male will hide while he is pregnant and color himself to match the surroundings and the female will always be on the hunt for pods and stuff,I have coral, clowns,and crabs in the tank, and no issues yet and its been about 2 years now, the horses are however really slow eaters so I leave the pumps off for roughly a half hour and always put little extra in the tank and they just go along the bottom eating as they go. Do little research first as the prefer cooler water temps.
