15gal nano for seahorse?

[Coderad]

Tank is 19"hx20"L 10"deep. The live rock is a wall across the back it is about
3-4" deep in most parts, there is room between and behinde some of the rock I am not sure what kind of sea hores. I will have a good skimmer I am doing the shopping for that now. I do 10% water change every 2 weeks.
I am not even sure seahorses is the way I want to got I just want to do something different with this tank and the seahorses are alot of fun to watch.

Thanks Cody
