I was speaking to a guy who has a thing for eels, I believe he has 4 now. He has a Japanese dragon eel as well. He said the dragon went for 62 days one time refusing to eat. When he finally did he ate a ton. That would freak me out, I would go into panick mode.No effect on anyone else, and about 30 minutes after the large water change Aku ate a piece of shrimp that thawed out of the LRS chunky. I offered a second piece, but he showed no interest.
