Best eel for a reef? This is a item which becomes a discussion from time to time. But as for reef safe all together, is truly another matter in which my suggestion after the thought of the SFE or zebra morays, I come to the dwarf morays of the species as one mentioned here. And I'm sorry> Ribbon Eel are far to aggressive when in need of food.
The idea in all this is that one has to consider the inverts they would have among having any eels and that were with more choices to have when a dwarf eel then having either the SFE or Zebra. That with housing dwarf eels, you cannot get too small a fish as well as inverts and such.
I'm still in plan for both my 180 and 240 reef tanks to have two different type of dwarf morays, a pair in each tank that I made this plan from the word go when I put down the first $3K for the 240 which was about 5.5 years ago. I think I give patience a whole another name here>
In any case, your a few choices when it comes to dwarf moray, only it will depend on which you be able to get and at what a cost. The dwarf golden moray that has a brownish color is far cheaper then the bright yellow golden color. Myself, I get me the bright golden color.
But no matter what the eel any of us have, we have ourselves a pred
ator in its own wright that if you were to house no eel at all, you not have to be concern about having not so small of inverts and such. The other thing be, if I was to ever wanted a Zebra moray again, in which I not> I would supply it with a live stock of crabs by having a small tank to hold the crabs and to place so many into the reef tank. Also this I would do for the SFE as well. The one problem you might have is that it would all depend on whom you know in where you get your live stock of crabs from.
