Well done! No doubt your stallion is feeling much better now that you have released the excess gas from his pouch and he can swim and eat normally again.
However, you should bear in mind that this may only be a temporary fix and not a permanent cure. Pouch emphysema tends to recur unless you correct the conditions in the aquarium that are conducive to problems with gas bubble syndrome (GBS).
If you will read through the discussion titled "can’t swim upright? sick??," you will find a good explanation of how to help prevent problems with GBS by making some minor modifications to your aquarium and water quality parameters, Jeanna. That would be a good place for you to start. If you copy and paste the following URL into your web browser, it will take you directly to the right information:
This would also be a good time for you to line up some Diamox in case the medication is needed to treat recurring problems with GBS. The same discussion thread explains how and where to obtain the Diamox.
Best wishes with all your fishes, Jeanna!
