When i caught this fish it was about 3", but now it's about 7". It's actully starting to catch up to my Oscar which is 11" in only half the time.
No it's not native to this island. These fish actully got introduced into our local streams from near by hotels during large rain storms. They actully aren't very common because the water temp. here is to cold, but sometimes i see them around. I guess some of them just adjust and the rest don't because when it rain, alot of them get out. The fish i have is a very hardy fish so i wouldn't be surprised if some of them would survive the water temp. change.
