Hi Titan, in a PM I requested that you posted this for good reason, to allow others to voice an opinion. Now I said i would have some answer for you from your PM questions and without further ado, here you are
I'm trying to gather as much info on the setting of a moray tank, so when the time comes I'll be prepared
That`s great, then maybe I can assist you on some thoughts to this. You see that for the eels I have that my tanks are loaded with lots of LR for as well it only houses a pair of eels in both tanks, not to mention a number of damsels that I use for eels are messy eaters.
Just as well, the idea in a yellowhead moray, you want as enough LR you can in giving this eel as much hiding places as well open area so being as it may, the yellowhead is a very active eel and the larger the tank can be the better.
Unlike the idea in what I do with damsels with my eels, it not be so good of an idea with a yellowhead so with this I can suggest to you not to have so deep a sand bed, like not more then 2.0" and be careful for the more LR one has the more currents be needed.
As you seen that my eel tanks have lots of LR and if you may tell not so deep a sand bed for I not know if you readied all I mentioned of these tank that they were moved more then 19 months ago and only twice I cleaned some by hand inside the tanks.
For as these eel tanks have a light bio load and both pair of eels I feed only once a week but this yellowhead you feed on average every 4th day and feed until it refuses any more feeding.
In this you will be needing a feeding stick, you might check and see the type of spear I made to feed my eels with>
Eels like the yellowhead and blackedge will attack your hand on sight when hungry so the idea of a tank 3x3', I would rather if I did this go with a 5' 125. and the most perfect time when you need to clean in this tank would be right after the eel had feeded and do avoid to near to the eels lair.
You will need to do with the glass covering is duct tape across the back of it and when you start to look in putting this tank together, being that you will get the yellowhead as young a juvenile you can, have your LFS measure the overflow box to fit as flush to the glass cover they can, this will prevent this route from becoming an escape passage.
The fimbriated compare to my eels I now do require more space

It`s not they require lots of swimming space for it`s rather to how active the eel is to anything else for it`s the same thing for the Tess and green morays, they need so much room over all in tank space that they can never manage to move around much once they ever reach their adult size for yes, the green smallest size is around six feet and can grow larger for as well the Tess, this animal is something to see if you ever go diving and not be afraid for if you`re in the swimming path of one these eels, they will swim right past you between your legs. The tank I would setup for a Tess would be not less then 2500 gals and the more the better for the LR would need to be huge pieces and as well bolted into position to build the Tess morays lair.
But back on your issues at hand
The idea of the 135 (3x3) is good for many eels, I just not feel as comfortable when the fimbriated reaches full size for yes, it grows no larger then my DME`s but it is one the most active eels around that people are always asking for.
I live in a fair sized city, but here it's reef madness
Nothing wrong with that
The reason I want the Eel alone, is I'm more likely looking at a fish eater not crustecian
The fimbriated does feed on crustacean as well and I say Titan, if anyone cannot feed this fimbriated moray, they can feed no eel. LOL :rollface:
I have no resource for live fiddlers
You can find one or more on line for if I was to own an SF or zebra moray, I would have up a 30 or 40 gal tank only to keep on hand as many crabs I can.
Titan, if you really want to have a DME, why don`t you check with all the LFS around you? And do be careful on the price.
I have to admit that I not know this H&S skimmer, but I do know of the ER skimmer, I have the ER on all my tanks and even the 40 breeder (QT)
So Titan, you want your eel tank to be completed before you get your eel of choice>
Buddy ><{{{{">
PS. Titan, you need to space your lines for it does somewhat give me a minor problem to understand everything your looking for info on
