I'm not really the one to talk about that, my male got bubbles in his pouch once, and has since made a full recovery.
when males are in tanks they sometimes get bubbles in thier pouches. its called pouch emphasema (sp?) it can happen because of micro bubbles from a skimmer/filter, or for other, not quite known reasons. AND it doesn't happen all the time, kinda a hit or a miss. There are lots of articles on seahorse.org on the treatment for it. recurring is bad, or you can have an isolated (so far!!!) case like mine.
the long and short of it, bubbles get trapped in the pouch of the male and can't get out, so in one form or another, you get to help him. Usually with the tip of a plastic-ended bobby pin. I just used the tip of my glass hydrometer... you slightly pull open the pouch under water, and the bubbles come out.
and thats the SHORT version.
