Loodachris, first thing is when one has so young a juvenile eel, you use it with any type of aggressive fish for it should as well be in a none aggressive tank and with all honesty, you will get different thoughts on the mixing of eels and triggers and by most can work depend on tank size and both eel and trigger to which they be for you would get quite different results. And myself in this area, the only way I would ever attempt housing a trigger and eel together is if I can have as large a tank that I might fit in my house for triggers, depending on which of this species can dance around an eel striking its colors taking nips at the eel in hit and run tactics and by most, the eel would be defenseless.
As well you will hear of those that will say it works for them, ask them just house long it did work before they had to made a change on having both because I believe that the majority of aquaria hobbyist not have a suitable size tank for keeping this mix for the life time of either species.
