Reminds me of the time working at a lfs
and the owner and myself were showing a customer some snowflake eels. They were babies only about 8" long and were all hiding under a rock. So the owner reaches in and moves the rock and while he hand his hand in the tank one of the little buggers tagged him. He pulled his hand out and thought nothing of it.
About a minute later the customer points down at his hand and the floor where a pool of blood was collecting from his bleeding finger.
Even though that eel was cute little baby, it completely shredded his fingertip,
funny thing is he didn't even feel it.
Respect the teeth.
