I have a rabbit. They are great! My hands are in my tank everyday because I feed my stingrays by hand. At first, my rabbit would hide and run, now he eats pellets from my hands. He also follows me around the tank, waiting for food of course! I honestly would not worry about it stinging too much, however I am in no way a fish expert.
I have never heard about anyone getting stung from these like the stories you hear about lion fish. My rabbit is very alert and cautious most of the time. When I put my hand in the tank, he is always aware of it, so he does get scared or startled.
Bossy - I saw mine nudge a new fish with his nose but that is about it. This lasted for a few days and it was not anything to worry about.
The net - he hates it! If he sees the net, he is gone fast, changes colors, etc. Funny how they know to run from the net!
Again, not an expert, just my personal experience!
