I can only imagine how big the mouth of the discus might have been to fit a cory or how small a cory could have been to even get stuck in discus mouth !!. Were cory's really that small during 2007 ? These days we see quite large ones though...and I think there are very few aquarium standard predators who are smart enough to even think of gobbling any descendants of catfish family regardless of its size..due to the most painful dorsal spine of a catfish !
