Hi Jay,I've never tried to tube-feed a seahorse. I have done that with weedy seadragons, but it is very tricky to do on small fish like that. You cannot use a pipette, you need a tiny catheter. Also, seahorses don't have a "stomach" per-se, so the amount of food you can get into them is miniscule.
I can't explain why this seahorse is not breathing fast compared to the last one. This tends to go against the idea that the cause is the same....
I would wait until tomorrow and dose the General Cure again. You can try a Ruby Reef Rally Pro dip, but I'm not confident that either will really work in this case.
As a side note - I still lose a lot of seahorses over time. They just do not survive for me as long as I think they should. With some (tank raised Erectus and pot-bellies) we've been able to breed them fast enough to offset the mortality rate, but we still have issues.

Just an update, as of 4:30 he still seems to be breathing normal. I tried lifting his hitching post to feed him with tweezers. He kept turning his head, and eventually seemed to get annoyed and swam gracefully down to another post. His eyes do seem to move around slightly.
That seems like a good sign. The bottle of Ruby arrived - do you think I should combine with the API General Cure, or don't do anything?
My fear, again, is he's rejecting food, no matter what I do, and I probably have 2 days left (maybe 3 at most) before he starves to death.
