Okay i see them now... must have been my computer.
1) Did you see that poop come out of him? Betta pellets look similar when they have been soaking in water for a bit (they are actually made of tightly coiled 'sausage' of food).
2) I am just trying to distinguish... is his spine bent sideways or down?
3) From the pictures he doesn't look bloated but it is concerned that he lays on the bottom. I also get the impresson that he just has a bit of a odd back... I can definitely see that his dorsal fin is se back a little farther than normal.
Again, I am in maple ridge and nurse him back to health in a quarantine if it is close enough to be worth it. If you want to hold off on a tank until boxing day sales, I suggest putting him in a rubbermaid bin/tub. Since most starter kits don't come with heaters in Canada, you can just buy it now separate form the rest of the tank and put it in the tub.
