ABC Wednesday: X is for X-Ray Fish

Those are Ghost Catfish (Kryptopterus minor), sometimes also known as X-Ray Fish. They are native to Borneo, about 3 inches long and only one of a whole number of species with similar looks.
Ghost Catfish live in groups of ten or more fish and prey on insects and smaller fish. They can reach an age of ten years and are often kept in captivity, although no-one has managed to breed them (as far as I know).
Just how transparent an individual fish is depends on its diet and habitat. Like all catfish, they have no scales and since they don't have any body pigments, they are transparent.

When I first saw the title, I thought that this must be a fish to keep clear of. It proved to be a very interesting post.

Well we are on the same page. The only X I could find was an X-ray fish too.

This was a hard one for me...!

This was a great post for X. I have never heard of X-ray fish before.

Transparent fish that look like an E-ray. What a perfect choice for the letter X.

That was interesting. I think it would be a bit creepy to be able to see right through each other, but maybe they like it that way and solid fish very strange
