How big can the turtle catfish grow?

A dozen centimeters.

The longest 3 1CM is mainly produced in Central and South America: Venezuela and northern Brazil. Estuaries will enter fresh water, mainly inhabit mangrove steam waters, migrate between fresh water and lakes, and breed in soda water, but fresh water will also breed in artificial environment.

Benthic fish are usually found in soft bottom water.

The giant turtledove cat has a unique reproductive habit. The female will hang the fertilized egg in the abdomen until it hatches, which can provide sufficient oxygen for the egg in a low-oxygen mangrove environment.
