I got it from bluezoo about three years ago. It's never harmed any of the shrimp. It occasionally seems agitated when they clean its mouth for too long but it just shakes its head and they scurry away.
Piscivorous eels are generally a safe bet with shrimp. It's the pebbletooth eels that you have to worry about.
The fimby has eaten numerous fish though(see pic<---). I used to buy damsels in bulk every few weeks to add some color and movement to the tank. As the fimby has gotten larger it has ignored the smaller tankmates and prefers large sections of octopus or squid.
I thought about adding a G. milliaris to the tank but I could never find one for sale that was as large as the fimby. If you bought a small fimby/goldentail at the same time they may work quite well together, just a thought.
