I have to say I agree with boxienuts. Taking one or two tigers from the wild isn't going to cause them to go extinct. Although tiger salamanders ARE being taken in large numbers every year in the midwest to be used for fishing bait (I don't know about the rest of the U.S.). Nearly every bait shop I've been to has tanks full of anywhere from a dozen to literally thousands of tiger salamanders for as cheap as $0.50 each...

And as far as breeding tigers in a 150 gallon tank, I don't think that's even big enough if your goal is to breed them. If your goal is just to keep the animals healthy, I have known people that have kept as many as 4 tiger salamanders for many years in a 10 gallon aquarium (not that I agree with cramping that many animals in such a small space). The salamanders I had that bred for me were kept year round outside in 10' or larger horse tanks...

Also, I understand since I was unable to raise any of the babies I got several years ago that it wasn't considered a successful breeding, but the animals that laid the eggs that hatched into larvae had been in my care for at least two years prior to laying the eggs. They were not gravid wild caught females unless they just stored viable eggs for two years... All I did was keep all of the salamanders I had in my "pond" year round and feed them as much as they would eat and they eventually bred. I know tigers are generally considered to be terrestrial (and that is how I keep mine now) but I have caught them in farm ponds all year round minus the extreme winter and that was just because it was too cold for me to go look... just some food for thought.
