additional stocking for a 135 gallon

Hello, I have a 135 gallon tank and at the moment I have a juvenile emperor angelfish and a yellow tang.
I was thinking of a Snowflake eel
Anyways

What will work with these fish with little to no aggression.

Thanks

 

Your emp will need a far larger tank
I don't see any large problems, the eel may go berserk but the other fish aren't tiny.

 

Snowflakes are less aggressive than some of the other eels out there so they 'berserk' level isn't as high. They are however a predator and like every other predator far less aggressive when well fed. Keep in mind eels require tanks with good lids cause they do come out at night and go looking around, without lid this quickly means checking out the floor. They are fairly common on the market and picking up a smaller one that has time to accept itself s being smaller is also a good idea.
