Looks to be a shortbody albino Channa argusCool! I admit my first thought when I saw those pics was amazement that Dats were so cheap over there that they could be used as feeders.
Question: What is that large fish in the tank on the right, in the upper right quadrant?
Should be weather/dojo loaches. Quite common choice of feeders amongst the Asian countries.Not barbs. Not loaches.
They have got whiskers, some some local catfish fry.
