It's fascinating to work with animals in captivity, because we can learn a lot; physiological data that can't be collected from wild individuals. Veterinary care. The fact that sometimes moving a stick that an eel liked a lot will result in them having a tantrum for six months

Okay A LOT of people are asking for description of eel tantrum:
1) all food is a personal insult now
2) dramatic side-lying; I've died, I'm dead, woe is me, etc.
3) multiple eels all cram under other sticks that were not moved and stare distrustfully at moved stick
4) bullying

Additional notes: The stick was moved to put MORE stick for better eel habitat. The most heinous crime ever committed

I have muted this thread as it has gone entirely off the rails, but final eelfact is that we printed this comic out years ago and it hangs above them forever and it is still hilarious https://twitter.com/dami_lee/status/773382218106474496
