Regardless of the point on benthic, seahorses have a tremendous propensity for picking up bacterial diseases, wherever the bacteria comes from, and by experience it has been found to keep the temps below 74°F for fewer problems. I don't have documentation, but I have experience.
When I started some years back, I figured that with 12 years reefing experience, I wouldn't have any problems with seahorses, even at reef temperatures. I would be the exception.....in spite of what I was informed on the major seahorse forum.
After loosing a couple of seahorses and a couple of pipefish, I dropped the temperature and haven't had a problem with them except when I went on holidays 1 1/2 yrs ago, the sitter turned off my cooling fans when doing a water change, forgot to turn them back on, and temperatures raised.
When I got home, the seahorses were seriously ill with the female loosing part of her tail. It took a long antibacterial treatment regime to save the seahorses.
If you check out the big seahorse forum, you will see just how important it really can be, and just how many have problems while keeping slightly higher temperatures.
In their natural habitats, there isn't a big problem but when in a captive system, elevated temperatures really boost bacterial growth.
FWIW, Ann would be the first person I would contact if I had seahorse illness, just as so many others in this hobby do. She has devoted her time to compiling information on seahorse illnesses and diseases, and then helping other hobbyists save their horses.
