Yep, not so bad.
It feels like a bee sting that's it.
Now I'm a tough guy but I have heard others it was a worse, how much worse I don't know as we never heard again from those hobbyist ;)
Just as with other fish don't handle them with your hands, just a net and direct them in a clear bowl or bag if need to be removed.
Always bag under water.
As for maintenance in the tank I never got stung by any fish in over 30 years, besides some stupid clown fish or a giant 1" damsel who thinks he was Jaws :p
