Seahorse in a Nano - Only fish...

[scary gary]

You do need the height for seahorses. I kept my 2 kuda's in a 15 tall for about 18 months before the male stopped eating and died. Finally got my hands on 2 new kuda's each about 2 1/2 inches long. My old female is about 6 in. long. Moved them all into a oceaniac 29 nano plug and play. Lots of room for them now. Dwarf horses need to be feed live food. Captive breed Kuda, Reidi, Erectus, and Kelloggi will eat frozen mysis. After seeing a couple of horses playing around with each other you would not want to keep only one.
