Hello! Yesterday I got a Albino Cory Catfish for my tank and today i saw that my 3 amano shrimp were missing.. is it possible that the Cory ate the shrimp?
Sounds like the catfish or one/both of your bettas decided the shrimp looked like a tasty snack. You could get more shrimp to see if they disappear also. Ghost shrimp are cheaper than amanos.
