Odd behavior of Acans

[Medic755]

While doing some maintenance I noticed that my Incredible Hulk Acans were acting, well, different. Usually increbily puffy and acting like a fat kid at this time of day I had never seen them act like this before, especially during feeding time. All parameters are exactly the same as they have always been. It looks like there is a tube protruding from their mouths. I have found nothing about this so far.

That was my though. It pulled it back in, and now last night when I got home it was back to it's normal, fat, hungry self. I love the little oddities of the hobby.
