Corydora Eating snails

Hi There, I have this one weird issue I have a few corydoras in a 60p tank. Wife recently added 10 golden white clouds. Now all those white clouds are gone. None of them jumped and yet only the corys are left. We have this one quite large albino cory and he ate 1 pagoda snail and 1 apple snail. As far as I know corys are seen as peaceful.. so am I not feeding them enough? They do have a varied diet of frozen bloodworms, frozen brine shrimp, sinking pellets and dried brine shrimp. Has this happened to anyone else or is this just a weird fish lol.

 

I have pepper corydora's with guppies, white clouds and snails and they all seem to be doing their own thing + the guppy babies dont dissapear So might just be a killer cory.

 

I've had them with dwarf shrimp and the shrimp colony still grew. Albino, bronze and panda Cory's

 

You are correct, they died (disappeared) over a period of a month. The day before I posted we had 2 clouds left, monday we had 1 left. When I got home on monday... no more white clouds. So got more white clouds, put 1 in an isolation tank and now I am testing every cory with that white cloud, if the cloud makes it 24 hours with the cory, we switch to the next cory.

To your point, could it just have been a bad batch of white clouds, since the corys are doing well.

 

So I isolated one of our albino corys in a tank with one white cloud. When I got home the tank had a well fed albino cory in it. I then added a white cloud to the original tank just to test if the rest of the corys could be guilty of the same behavior.

 

So the single white cloud with the rest of the corys was alive and kicking. Seems my albino cory was trying to be a great white lol. Thanks for the input guys.

 

Corys aren't even equipped to hunt down or kill fish. They have no teeth and aren't fast enough. They aren't predators but scavangers. Sorry to say but I seriously doubt the Cory caught and killed the whitecloud (super fast fish as well living in the upper part of the tank)
