The reason they strike out so much is that they are almost completely blind.
This type of eel has pretty good eye sight, I would consider it above average compared to other fish I've kept. It is pretty aggressive though, and since it has associated anything entering the tank as food, and it associates my hand with food, it assumes what I'm holding is edible from the way it reacts. If I leave my hand still in the water it will come around to where the tips of my fingers are and wait for something to drop.
Also the tank is about 3' from our 45g freshwater tank, it can clearly see the fish in the other tank and will often dart towards the tank when the neon cardinals swim by. It also follows the cat toys around the room when I'm playing fetch with my cat.
I moved my Flame Angel into the same tank with it, surprisingly the eel struck at the angel once, but the angel has the eel cowed. It turns sideways towards the eel and flashes towards it, the eel doesn't even look at the angel anymore.
From all of the information I've been able to find about them, they only grow to around 18", so it maybe has another 7-9" to go, pictures of full grown adults of this type appear to look more like stretched out groupers as adults than looking like a eel. It will develope a large forehead and almost hump back, like a freshwater clown knifefish, or panther grouper. Not as pretty as a moray, but fine in it's own right.
