I bought a stingray 2 weeks ago and he has been eating drinking and swimming fine since I had him. I have a 60 gal
tank (48" wide) and he was about 3 - 4 inches including tail. everyday he would eat from my hand fine and got along with all the fish in the tank. about 5 days ago he got sucked up into the inlet of the power head and when I noticed I immediately unplugged the system and he fell out. His head was a little swollen but after an hour he was back to normal and the swelling went down just leaving him a scar of a ring on his head. Since then he has been fine eating etc. and I came home and he was dead on the sand bed...
Could he have maybe got an infection from his accident that had killed him?
Water to warm for him?
Any other possibilities?
Info on the tank:
size: 60 gal
bed: soft fine sand with a lot of open area
temp: 80-81 F
filtration: sump w/ asm g1
