Hippocampus kelloggii is also known as the "great seahorse" in the US/English speaking regions. It averages in and around 15 CM (6 inches) but has been known to grow up to 28 CM (11 inches). They are most commonly found in China, India, Indonesia, Japan, Maylasia, Pakistan, The Philippines, Thialand, Tanzania, and Viet Nam. They are suspected to be found in many other areas to include the Gulf Region (Kuwait, Quatar, Saudi Araibia etc.) In Viet Nam, they are called "Offshore Seahorse" which should tell you a little more about the species.
They are common in depths averaging 120M and prefer soft substrates. They associate with gorgonians and sea whips. With that said, you will want at least 18 inches of water column, a soft, sugar sand substrate with hitching posts to include whiplike structure to more adequately replicate gorgonians and fans. As with all seahorses, they need low flow, high skimmed or filtered systems. Plenty of
live rock to aid in biological filtration makes sense to me. Standard
PH, Temps in the range of 72-76F.
SG 1.020-1.025 should be fine.
They are VERY slow eaters and should not be kept with other agressive feeding fish. Wild caught fish are tough to train on frozen foods. Also keep in mind that Kelloggi is one of the most mis-identified fish in the hobby. Most are found to be hybrids.
