Why Can’t Turtles Eat Fish Food? A Must-Read for Mixed-Species Keepers—Beware of Edema and Kidney Damage!

Many people enjoy keeping fish and turtles together, finding it convenient and aesthetically pleasing—but a moment of carelessness in feeding can lead to a bitter lesson!

A Real Case Warning

Have you ever considered this: fish can occasionally eat turtle food, but turtles must never eat fish food! Why? A turtle hobbyist (turtle enthusiast) once experienced a real tragedy: a well-acclimated and hardy (meaning the animal is robust and not prone to illness) Chinese Pond Turtle, after being placed in a fish tank, was only fed fish food by its busy owner. When the owner checked on it again, the turtle already had severe edema all over its body and ultimately could not be saved.

Analysis of the Fatal Cause

Here’s the fatal reason: the vast majority of fish foods contain salt content and additives (used for mold prevention or to promote fish growth), which are “kidney killers” for turtles! Turtles have an extremely poor ability to metabolize salt. Ingesting it can easily lead to kidney function damage. Once kidney failure occurs, the body will quickly develop edema and it can lead to death.

Feeding Principles for Mixed-Species Keeping

For mixed-species keeping, remember this point: fish can eat turtle food, but turtles absolutely must not eat fish food, though occasionally it doesn’t cause much harm! If you are also keeping them together, please make sure to specifically feed your turtle its proper turtle food, dried shrimp, or freshwater fish meat. Don’t let negligence cost a “turtle’s life”!

Protect your beloved turtle, starting with correct feeding.
