Thanks for your input. I"m thinking the same thing you are. He doesn't seem to be hurting himself and as some have said on the thread, it seems like a good workout for him to work off the occasional bloodworm binge day I give him twice a week. I checked the water conditions again and they're good - 0.25ppm ammonia, 5ppm nitrite/nitrate, ph 7.4, temp 78. It's been 3 days since a 50% water change. I'm planning on doing a smaller PWC today.
The links seem strange depending on how you get to the thread OFL. When you click on the email that informs you there's a new post on the thread, it sends you to the thread using bettafish.com and if that happens, the links created in TropicalFishKeeping.com don't work. The links do work if you get to the thread by going through the forum in TropicalFishKeeping.com. Sort of strange link behavior, and I think it's because bettafish.com doesn't have the option to automatically parse links in text, but eh, I'm not a website guru.
