I just got a betta boy a few nights ago from Petco and it looks like both his gills are permanently swollen so they stick out from his head. From what I've researched on nippyfish.net, this is gill hyperplasia? Is there anything I can do for this little guy? He does seem to breathe a bit heavier but he doesn't appear to be desperately ill. He's not super active but not lethargic and listless. More like . . . cautious, like he can't believe he's out of that tiny, dirty cup. He hasn't eaten yet either. When he swims, he never uses his ventrals. He's an odd little guy.
Should I try to treat him with a medication? Nippyfish.net advises adding AQ salt but I can't do that on a long-term basis. I just want to help the little guy feel better and breathe easier (some pun intended).
