Tessalata and Zebra morays are leading candidates!
Both get over 5' though man...you'd have to upgrade down the road probably but I do agree they're cool looking
Those two species will be perfectly fine in there for life...
Why do you say that? 5' is almost as long as his tank and is over twice as long as the width of his tank...the eel would be crammed in that size tank if housed for life (I would think).
Their behavior is why they do not need a huge aquarium. Consider the fact that they spend the vast majority of their time in their dens waiting for a meal to pass by; they enjoy tight spaces as it makes them feel secure. They're like the fish equivalent of a large snake and can be cared for as such.
Besides, why would LiveAquaria.com and numerous other reputable sites say that a 180 gallon aquarium is the minimum?
I will take that into consideration. Is 5' the wild ocean max length or is it commonly achieved in an aquarium. If it is I will take those or which ones do grow 4+ feet in aquariums off my list. Thanks for all the info guys.
