It escaped the tank once, but learned not to do it again. How it died, it got a pretty large wound on it's tail. Didn't make it through the day. At least peacock eels are easy to find these days.Sorry to hear about your peacock eel. Did it escape the tank?
I’ve found that spiny eels are a lot more personable than most other fish. That alone makes them a lot of fun to keep, IMO.
