Seahorses will often hang upside down from a convenient hitching post when they are hunting for pods and searching the substrate for suitable prey.
Lying flat on the sandy bottom is unusual. As long as your water quality parameters are where they should be, and you have good surface agitation and oxygenation, the only other times a seahorse would be lying flat on the bottom of the tank is when it is so weak that it doesn’t have the energy and strength to perch normally and hold itself upright from its hitching post.
How is your tiger tail (Hippocampus comes) eating, sir? Is it well fed and getting its share to eat at feeding time, or are the other fish out-competing it and stealing the frozen Mysis before your pony has a chance to slurp it up?
Is your tiger tail breathing normally, Eric? No labored breathing or rapid respirations?
No, sir, I know of no other breeders or dealers who are offering tiger tail seahorses (Hippocampus comes), sir.
Best of luck with your young tiger tail.
