I too have found many things inside fish. I once caught a rather large Blue Catfish that upon cleaning the fish for fish fry,, I discovered one Approx two pound carp AND a softshelled turtle.
On a somewhat related matter,, Many small fish such as Bettas,Tetras,guppies,etc have considerable trouble with foods such as krill,shrimp,and bloodworms.Their mouths can accomodate these foods but their throats are quite small. Often times these foods can become lodged and cause the fish problems. I recall one gentleman who performed necropsy on Betta and discovered that the fish ,who relished the freezedried shrimp ,had actual scarring where this food had damaged its throat. The fish tried to eat but kept spitting the food and eventually died. Also have heard or read that bloodworms can cause si milar problems.
I try to soak the foods offered to small fish before feeding ,and I use razorblade to chop up these foods. I am not real keen on frozen bloodworms or tubifex worms in any form. I have no concrete proof ,,but all other things being normal,, I have lost fish feeding these to them. Could have been a batch that was not properly stored or perhaps some parasite. But I stopped feeding these foods (bloodworms,tubifex.) and mortality rates were reduced significantly.
