Iguana loses his tail...

When I was a kid, my sister had a small green iguana, "Seth." She had outfitted a small aquarium we had lying around as an iguana habitat for him. The aquarium was too small for him, though we didn't know that at the time. One day, my sister's friend had her hand in the aquarium to pick up Seth the iguana, Seth was
freaked out and ran away from her hand. All at once, his tail whipped against a big rock she's out into the aquarium and, wham! The tip of his tail snapped clean off. The stump was oozing a little blood, and the iguana wouldn't stop running around the cage. We were totally freaked out, but my dad was a quick thinker.
He managed to catch Seth, and put some cornstarch powder on the tail stump, which stopped the bleeding at once. We were worried about Seth, but Dad kept saying it was okay, that lizards lose their tails all the time, but can grow them back. Once Seth stopped bleeding, we managed to get him out of his aquarium and
cleaned the bloody dried powder from his tail stump. From there, we consulted a friend of ours who had a giant, old iguana and asked what to do.

On his advice, we put iodine on the tail stump every day for about two weeks, after which time the stump was healed. We realized the reason Seth had been injured was that his cage was way too small for him' he was already pretty long, and the teeny aquarium was hard for him to turn around in. We got a much bigger one soon after, so that Seth had enough room to run around without any more tail injuries. Seth's tail did regrow a bit over time, though it never looked quite the same; the new part was much darker than the rest of his skin, but when a vet saw him for a checkup a while later, we were assured that this was normal. As of today, Seth the iguana is still alive and doing very well. Once we realized he needed more space, we were dedicated to building him bigger and bigger habitats whenever we could. He is now almost three feet long, even with his shortened tail, and lives happily in a custom-built terrarium in my room; I adopted him after my sister left for college.
