I threw in some frozun cubes, and the 8" Oscar swallowed it. It bareley fit in his mouth. So it made me wonder, can get a brain freeze?
 
Well, you get a brain freeze from something very cold touching the roof of your mouth.
 
Well, theyre cold blooded, so eating a frozen cube must cool them down a bit, but I dont know how bad it is. Ive been feeding one of my tanks frozen bloodworm and brine shrimp cubes for a couple years, and the fish in there take them down whole, and they are still fine. My dempsey often will hide by himself ater he eats a whole cube, and he doesnt do that after eating non-frozen food, so I always thought he must have cooled down a bit from eating it. I dont think theres any real adverse problems though, but I could be wrong.
 
Was he squinting and rubbing his head?:ROFL:
 
No. Brain freeze has nothing to do with your brain getting cold. It is when blood vessels in the roof of your mouth contract due to the cold and then expand again due to warmth.

Its possible that eating frozen chunks of food could hurt the fish though.

:ROFL::ROFL::ROFL:I wonder what he would do, if his fins could reach his head. Then we would know the answer.
 
my O would grab cubes of frozen beef heart, and hold them in his mouth until it thawed, then swallow it. It didn't seem to bother him. but then, I wonder what kind of pain that pig would actually tolerate to get some grub in his belly.
 
I thought you weren't supposed to give them actual frozen food? I was always told to defrost the cubes in a cup of tank water, then give it to them like that. The ice crystals can do internal damage or something?
 
i highly doubt an ice chunk effects the temp of a poikilotherm, yet i have seem my small dat eat a piece of frozen food and react somewhat strangly, i think they have hard time swallowing it, and i know that the frozen chunk may seem to be larger to the fish than when it melts.
