This is the video of them getting transferred into the 25,000 gal carp exhibit.
This was the first attempt. It was unsuccessful because the various mahseer decided the esoks were their new chew toys (they didn't touch the lemon fin barb, nor the small scale mud carp though), so I had to snorkel in there and catch them a few hours later and place them back in the same 240 gal.
A month later or two, when all the gnawed out scales grew back and the damage healed and more importantly when I had realized that mahseers simply needed to be fed more and then they left the tank mates alone, I tried the same again (wasn't filmed) and this time it has been a resounding success.
The esoks have been doing very well there and feeding enviably and growing.
