One of my albino Cory cat fish are missing!!

[I_love_my_bettas]

Hi so I have a 10 gallon tank with one docile male betta, one mystery snail, 3 ghost shrimp and one albino Cory catfish, but yesterday I bought two more for my tank and well I woke up today and one was missing? There is no trace of it anywhere I checked if it had possibly jumped out of the tank and I checked all my hiding spots, checked my filter, and non of my fish seem to be bloated out of the usual, I even checked behind all of my plants ans my rock/gravel substrate.. I would think it would be out and about with my other Corys but it isn’t, it was the smallest of the two.. just missing without a trace.. no tiny fish body.. no skeleton.. just gone.. has this happened to anyone else? Any tips?

I'm guessing it died and then your snail probably ate it.
Your tank is too small for your cories. You need to have a school of at least 6, and that would overstock your tank. Also, cories need a fine sand substrate. Those rocks are not good for them.

Yep I have to agree somewhat with what was said above.
