Dont know if this has been answered but regarding the tesselata eel:
I had on from when it was 6" until it was 18". This was only about 7 months time. They were, by far, the most aggressive and dangerous creature you could put in a tank. In my tank I had a niger trigger, clown trigger, clown grouper and a porcupine puffer. I had to get rid of the eel because his agressive nature, strength, and speed literally made it impossible for my to feed my other fish.
Pros:
Very active for an eel
Striking coloration
Cons:
Fast grower
Big appetite
Agressive towards fish (and your hands)
