the same thing happened to one of my florida gar. it ate and ate and ate and it was almost twice the size of the other gars and one day it just died coz of over eating..i still think about how fast it grew and how thick it got..sorry for your loss
Something about all this seems wrong and something else is involved.. But I do have to say that I never just let Gators just keep eating for if you do that is exactly what they will do. They do not seem to get the concept of limits...
I'm not sure about just why the Gator died. First I've heard of something like this in any Gar species. On growth though I had a similar fish. One gator I have would not grow past about 8 inches and even became known as the Bonsai Gator for just not growing. It stayed at about 8 to 10 inches for about 2 years. Funny thing is then it exploded in growth and reached well over 24 inches in less than one year. I really have no idea why there was a delayed growth.
whole thread is just pointless conjecture and guess-work without pics...even though the fish died (and actually especially since) we should have some pics so we can better investigate the issue.
at this point we may as well assume it was an alien that was going to burst out of it, but the little chest-burster couldn't make it completely through the ganoid belly--
secondly, i thought you had to get rid of all smaller gars???
