I bought it from an lfs, they do not know where it is from.
The fish is about 4 inches and very active even in the day. It's current diet is bloodworm, minced market prawn, and torsat (small catfishes).
Thanks for your responses and feedback.
It's definitely in the ariidae family and based on the pictures I can find online, Bagremarinus , or gaff topsail catfish does look like a definite possibility.
