im no expert but are you sure the fish didnt die then fall to the shrimp? amano, as far as i know. are best known as alge eaters!! think their hunting skills may not be up to catching and killing a fish. if im wrong be sure i will be corrected! lolthey just called it a "freshwater shrimp" at the shop i got it from. Looks like it might be an amano shrimp. Clear body about 5cm long
