Is This 'normal' Behaviour?

[Fintastic!]

I was checking on my aquatic friends last night only to see Dyson, my adult Bronze Cory, was literally buried in the sand. only his tail-end was sticking up from the sand and he wasn't moving. So I thought he was dead and I panicked. I got my net and gently nudged the sand around him expecting to scoop up a corpse, but he started to wriggle and dashed off to the back of the tank. A few minutes later he was acting perfectly normal. What do you think?

Sounds very much like my albino's

I made a mistake there, meant to say my albino cory! Interesting. I've never seen him/her do that before. Gave me a fright!

Sorry Harlequins, off topic but I've just noticed in your sig that you have albino babes in your 7 gal. I got an interesting picture in my mind reading that!
Just me being naughty...
