Mystus castaneus?

Previously identified as such but what makes me question is its size which is 20cm or a bit more. Cat-eLog says it should be 15cm. Also, it's not really brown, grey rather.

It's been living in the tank around 15 years and is still roaming around wildly (not easy to take photos of).

The sizes in the Cat-eLog are Standard length, so not including the tail, and they are generally correct "to the best of our knowledge" - which means that if you or somone else can provide good evidence to show that it's incorrect, then we'll fix it.

A photo, with a ruler next to the fish, clearly showing the scale of the ruler, is sufficient to change the Cat-eLog.

I can't comment on the ID, but I wouldn't rule it out simply based on the max-size in the Cat-eLog - it can be "low".

Yup, the ID is correct. I have seen wild-caught specimens of about 20 cm SL being sold in markets for food.
They are often much grayer when adult (although the wild ones typically have a yellowish sheen when freshly dead).

So, HH, do you think it's fair to extend the size to 200mm SL in the Cat-eLog?
