Re:pete, help!

Thanks so much Pete. Just got home today, and he still seemed fine, just floating upside down, although still latching fine.
I read the article below ‘upside down seahorse’ and decided we’d give that a shot first, as we are a little apprehensive about the needle aspiration right now, and not sure how to come about the antibiotic without going to a vet.
We tried to burp the pouch and seem to have gotten a little bit out. His belly still seems very bloated, but I am unsure if that is just because he is pregnant.
A little bit of bubbles came out, but not too many, and when we release him, he is swimming pretty rapidly around the tank with his body upright for the most part, but his tail still in the air above his body. Does this mean that some of the air was released in his body. My husband and I suspect that there may be air trapped mostly in his tail now as there is a little pouch at the base of his tail which we haven’t been able to work out yet. Any tips on this?
We are going to try and get some more air out with the massage later, and if not, we are going on a hunt for a small syringe and will try to do it that way.

Also, we have had him for about 3 weeks now, and still no babies. Is this irregular? Is there a chance that the babies could have just been air the whole time (although he was nice and plump and swimming fine until a few days ago when I wrote the first post). How long is the usual gestational period for seahorses? The only thing we did see (as I mentioned) was him pumping and his pouch opening 2 Thursday ago, but had to leave before we saw any babies.

Thanks again. Any more tips, or input would be greatly appreciated.
