We are generly speaking about a shy creature in which will take a long time before you might ever see it venture into the open, but it will most never during daylight time venture into the wide open areas of the tank. Even that I had one in its own tank for years and not once did it come out. But then again, im to in time will have a pair in either my 180 or 240 reef tanks for im to get as well a pair of red face morays and these grow no larger then 7". Now the tank the single dwarf golden eel was in, was a 30 gal tank, with a sump. Your eel will move about at night under the darkness So at most to when it will finally show itself, the dwarf eel will not move to far from the rocks.
Like in the wild, the majority of the eels will never come out until after dusk. Like look at this, many who eels get out of their tanks, when is this discovered? When the hobbyists get up in the morning, and why is this? Eels are generally active at night. But it never means that you will never see the little guy/girl. also not that any aggressive fishes that pest your eel would cause it to most likely never come out during the day.
Its like another person I readied that his a very young juvenile sfe in his tank with triggers and he wanted to know when will his sfe finally feed and I told him not until he places the sfe that is 6" into its own tank. If you gone with a sfe yourself, your a far better chance to see it before you see the dwarf golden moray.
On the feeding, you will feed it a long with your fish and corals that feed on chop fish, shrimp, squid and ect You will also best until the eel figures that its safe enough to move around some that you look to target feed it using a long plastic tubing object and try to keep a watchful eye out to what if it feeds or not, and this can take some time. of all the eels I had through the decades, the one which took the most time before feeding was Gymnothorax nudivomer (Starry moray). It was during the time, sometime after I became serious about eels, there was little data about to assist me in knowing what I had. But still, this eel has a toxic slim and the one thing I not knew for sure back then, was how large it can grow. I sold this eel to an aquarium zoo some 45 years ago. But this eel took seven months before it finally fed and thank god the eel was already a little more then 4'.
Eels feel secured in what is a normal home for them, for a good number of eels borrow themselves into the soft sand and usually using their tails and the rest must have a well built lair that they can hide out in total darkness. In all eels diets, must be a variety of types of foods. For if a hobbyist feeds only one or up to three kinds of foods, like there is one that I already know about. But I not blame him for this, but rather what advise his gotten from his LFS or so for he been not feeding it any fish or octopus for the nearly six years he had the eel. I already touched base with him on water changes and he will attempt to feed small thin strips of fresh fish every other day. But being that the eel is not as healthy as it should be, my concerns for this eel in the long term is that it will not survive a long hunger strike and asked him on how he felt about force feeding.
In any case, these are main facts to my own personal knowledge when it comes to eels. If you have a sudden shift in your PH, it affects their diet. If your nitrates are too high, it affects their diet. Poor water quality affects their diet. You cannot have a sudden shift in PH and correct it with buffering it and expect your eel to feed, for mostly, the eel will not feed at that time. Now you will have a dwarf eel in so hugh a reef tank, but normally in FO tanks and those who do a very large water change, not expect your eel to feed that day.
Of course, this not apply to exactly every species, the most aggressive and larger eels like the yellowhead, tess morays, and a very few others like the viper moray, and I not mean the viper eel that grows around a foot long, I mean the larger viper species who is extremely aggressive, and also the blackedge moray is another exception to this.
Now when getting this dwarf eel, not expect it to feed right away even in the lfs, what you can mostly go by if the health of this eel is in question, watch it to see how aware it is or if any activity and check its skin coloration for if it looks good, no fading areas or so. But to when the eel will feed, I cannot tell any exact time period to when this will happen for each persons eel. The point here is, if I had the eel, it would feed anytime in a matter of a few days, if not the next day. and depending on which eel the hobbyists gets, you can be extremely lucky to get one that feeds even the very same day. But on average, most eels will and should feed in a manner of days.
When you get the eel, prepare it very slowly for a few hours with a slow drip, for all a hobbyists can do is all the best from the beginning. Also not forget, im sure that your PH is a great deal higher then your LFS, for at most, every LFS keeps their salinity at 1.019 and when I start the 18o SPS tank, the salinity will be at 1.025-6.
On my question to you before was not on just any anemones, but if you had yourself any carpet anemones for this would be a danger for a dwarf eel.
I hope and trust that I had answered your questions without leaving you with more questions and if so, you have my permission to ask them.
OOPS!! :hammer:
how long before he will come out and eat,typically
It may never come out in the matter you want it too, just be happy when it feeds
Good luck with the little fella
