When I was doing salt I had a dragon mess with the lion and the lion make it a point to swim down to the eel and throw him self onto the eel stabbing him in the side.
I was shocked the lion did this in the first place. The eel wasn't happy and pretty much was injected with venom. The eel wasn't in too much distress as he did calm down after about 3-4 minutes of knotting himself up and trying to rub the injection site. He was a bit lethargic for a few hours but the next morning all was normal. The eel never again messed with the lion.
So, my opinion is you will be fine.
