All I’ll say is that risk is very little.
I work around 2 (maybe 3 after today…) in my own tank and have worked around countless in an LFS. If you just watch their behaviour and go slowly without any sudden movements they’re absolutely fine!
Here’s my Bicolour - I also have a Magnificent who is much larger (the biggest fish in the tank).
Agreed. I have a foxface in each of my frag tanks and they all will move to the other side of the tank whenever my hands hit the water.
Fwiw, I chose fox faces specifically for their utility. They are excellent hair algae eaters and will knock out bubble algae as well.
