Martin Glatz, a professional fisherman who was fishing with his twin brother Oliver in the Netherlands, was so suprised after he caught an astonishing bright yellow Wels catfish.

The huge species, which are native to lakes and rivers throughout Europe, weighs about 130 kilos and, if it survives to maturity, can reach a length of 2.7 meters.

However, leucism, a rare genetic disease that results in a reduction in the amount of melanin in skin and hair, is said to have been found in the fish that Glatz captured, rendering it a vivid banana yellow color.

Leucistic animals find it challenging to hide and survive in the environment because the discoloration makes the color so vivid and dazzling that predators can easily see them.

Glatz took the fish out and was taken aback by it that he dropped it back into the water, but he succeeded to take a picture with it. The list of the biggest fish found in freshwaters around the world includes this enormous species.

Glatz stated of the fish that “I have never seen a catfish like it before and I am still in awe of it.” Glatz hoped the fish would get even bigger despite its already outstanding size.
