I'm wondering the same thing. I've had mine for almost 2 months now and it is still red around the outside of the post! :(
No more than 2-3 weeks. But, if you hit it or snag it of course it might get red but the constant discoloration shouldn't last long.
If its been red,itchy and swollen for more than 2 weeks, if theres yellow/green drainage from the piercing.
When you first get a piercing, redness aroud it is perfectly normal. Depending on where it's pierced will determine how long it's going to stay irritated. Most of the time a piercing will be red for the first 2-4 days and be swollen. If it persists then I'd go back to the piercer.
depends where you piercing is
How long a red tailed catfish can stay out of the water depends on the fish in question and how moist the fish's gills are.
as long as they want to
it will stay a red giant for a couple of million years
