my gar. one of my top 3 best fish, alongside the blood parrot and the synodontis eurpterus. He was doing great and was given goldfish every 3-4 days. he was breathing well, had no signs of illness. I go to my friends house for an hour on friday, 13. beffore I left I checked on him and he was fine. When I come back my friend comes with me to see the 2" mouth. I have a bag of feeder golds in my hand and look at the surface. no gar. Thinking he jumped, My friend and I looked around the floors. I look back at the tank and see it dead, a plant stoped him from sinking to the bottom. My friend got him wish, avery detaied look at the mouth. I enspected the decised fish. no external diesises, full fins, no scraches, he wasn't attached. What Happened??????????
