Thanks to everyone who gave encouragement and solace in my "getting old" thread a few weeks ago. http://www.tropicalfishkeeping.com/b...ng-old-104954/
Along with general malaise, over the last month his abdomen has been swelling. This has impacted his swim bladder....that is he doesn't seem able to fill it. This makes rising difficult, so he stays in his plants near the top. He still eats and defecates, but not as much as before.
Is this just another sign of aging, or is there something I can do about it?
