I've had my Golden Dwarf Moray for about 3 months now and he is my absolute favorite fish. I wanted to share my experiences with it so far and I want to hear all about yours as well!!

What I want to know is: Temperament, personality, if its shy or not, what you feed, how often you feed, how many you have or had, what tank mates you have, if it's eaten any tank mates, issues or bad experiences with your eel and any general advice or info to share. Pictures of your GDMs are also encouraged! I'm very interested to see what people have to say so ramble away:D

About the tangs.. I know the tank is too small to accommodate them but they are still really small about 2-2.5 inches. I will re-home them once I feel they are starting to outgrow the tank so no need to crucify me =)

So on to the headliner. After doing some research, I chose to get a GDM because they are the most reef safe eel and I was attracted to their small size. I finally found a local seller who had one for the awesome price of $150. I couldn't pass it up so I drove my happy *** down there, excited to get my first marine serpent.

Upon arriving, he told me the eel kept swimming up into the HOB filter and the stubborn thing refused to ever come out. Eventually, he let it stay there after getting a nasty bite during an attempt to get it back into the tank. Their reputation for being escape artists started to become obvious.

The two of us started to dig the eel out with small fish nets. For about 30 minutes, we kept getting splashed and nearly bitten trying to scoop him out. Feeling defeated, he finally took the filter off the tank and dumped the water into a bucket. Thats when I got my first glimpse of him.

I was pleasantly surprised at how tiny he was, no thicker than a pen and about 7 inches. He immediately started lifting his body out of the water, stretching as high as he could desperately looking for an escape route. After multiple attempts, we managed to get him into a bag and I could finally take him home.

Ohh this eel rodeo was far from over... After floating the bag I dumped him and the water into a tupperware container for drip acclimating. I covered the top with a piece of acrylic to prevent him from escaping. Within moments, he started lunging towards the top, smashing his nose against the cover trying to escape. I could not believe how badly this thing wanted out, it felt like I was containing a ****ed off gremlin, minus the fur. Once acclimated, I had to dump him in a deep cooking strainer, covering it with the acrylic and finally, plopping him into the tank.

I was told that these eels usually don't eat within the first few days, sometimes weeks, when introduced to a new tank. On day 2, I offered him some krill on a feeder stick to see what would happen. He instantly took the food which was not what I was expecting but nonetheless, was relieved.

Within the first week everything was going great. He never bothered any of his tank mates and would even let the cleaner shrimp pick in his mouth for scraps after feedings. On the other hand, the fire shrimp will literally try to rip food out of his mouth as he's scarfing it down.

Around week 2 I came home one day and checked up on the tank. I couldn't find the eel anywhere. I looked in the overflow but nothing. I started looking on the floor and even under the tank stand, worried that I might find dried eel jerky but still nothing. Then I checked the sump and after a few minutes I found him..... poking out of the rock rubble... He managed to get into the over flow, swim down the pvc pipe into the filter sock, then crawl out of the filter sock and into the fuge. Absolutely relentless little creature...

Getting him out from the rock rubble was an absolute nightmare.... as you can imagine. lesson learned and I decided to cover the pvc openings with that mesh thing that comes with the veggie clips for nori. It's basically a mini version of chicken wire thats coated with plastic. The holes are large enough to let bigger debris flow through but small enough to prevent the eel from slipping through. Works like a charm. I also covered the gaps along the glass top with masking tape and poked smalls holes in it to help with gas exchange. It looks ugly but until I can find a more aesthetically pleasing solution, this will have to do. At this point I didn't want to take any chances. If you're thinking about getting a GDM, I strongly advise you make your tank escape proof before getting one. If theres a way out, they WILL find it! Wouldn't want your dog or cat eating gourmet sushi...

So onto feedings. I try to feed every 2 - 3 days. He gets a majority of krill and I'll throw in some silversides, raw shrimp pieces, or clam once or twice a week to mix it up. He'll indicate when he's hungry by starting to "hunt". He'll move about the tank, in and out of the rock looking to snack on something. Thats when I'll feed him until I feel he's had enough. Then he retreats to his favorite hole where he sticks his head out of the rock and sort of hangs out all day, until he gets hungry again.

For the most part he's left his tank mates alone. I had a purple firefish before getting the eel but it disappeared a week after he was in the tank. The firefish rarely came out of his hole and when I feed the fish, he would never go for the food. Maybe he starved, maybe the eel got him... regardless he hasn't been troublesome since introducing him, at least to my observation.

Then, about a week ago, I purchased 2 Sally lightfoot crabs. After placing them in the tank, I observed my new additions like any happy reefer would. Not a whole five minutes later, I notice the eel started "stalking" a crab. This was happening front and center in the tank, I felt like I was watching Animal Planet but in real life and without the annoying commercials.To my amazement, the eel actually snatched it and started shaking violently. Almost instantly, nassarius snails start popping out of the sand to scavenge any broken off crab legs from the thrashing. It was the first time I've seen it kill anything in the tank. I wasn't even mad though (well, maybe a little) because it was amazing to observe. The next day, the other Sally crab was gone. 2 days, later my coral banded shrimp disappears. Then, my peppermint shrimp and then 1 of my 2 cleaner shrimp.

I haven't fed him since he started chowing my tank inhabitants because I knew he'd probably be full from all the slaughtering anyway. Big mistake. Today, I woke up and saw my midas blenny with a giant bite mark by its tail. Luckily, nothing was bitten off but it still looks really bad. Poor blenny.. He's still swimming like he normally would so hopefully he'll make it through and heal up.

After the midas discovery, I decided to feed him some silversides as he was obviously hungry. The instant the first piece hit the water, the eel comes springing out of his hole with a vengeance, wolverine style. I've never seen him attack the feeding stick so hard and so fast and the first few strikes he actually missed before he landed the bite. I'm going to up his feedings to hopefully curb his hunger for my tank inhabitants. Do any of you experience increased aggression with age in your GDM or when you forget to feed yours?

Despite some of his less desirable tendencies, he is still my favorite fish. I love seeing him stick his head out of the rock with that menacing but at the same time adorable gaping mouth. They kinda look like they just told you a bad joke and are waiting for you to laugh.

For the most part he is always visible in the tank. He is far from shy and sometimes will swim out in the open, then recede to a different hole and hang out for a bit before moving around again. I actually want another one as I've read they do well in pairs. If any of you GDM owners have more than 1 in the same tank, let me know how its going!

My experience so far has been very interesting. I've read people having similar experiences with theirs and others with completely different ones. It really does come down to the individual. Do share and spare no details =)

Happy Reefing!
 
One of my favorite guys in the tank. Had one for 4 years and he hasn't attacked any tankmates. Yours seems extremely aggressive. Can you post a pic or video?
 
He's insane! Might be kind of why I like him so much. Wish he wasn't messing with my livestock though =\.

I'll try to post some pics later today when the main lights go on.

I have had mixed results with these morays. They are very hardy but the larger ones can and will eat smaller fish. I have also purchased so called "pairs" and they would bite each other. The wounds would heal quickly but you could see the scarring afterwards.

I have a buddy that has a couple that are very yellow. (as yellow as a banana moray throughout the entire body)

The ones that I purchased from a diver in HI varied quite a bit in coloration. Some were whitish. Others were very bronze and some even had markings on them.
 
I have a small specimen that is bright yellow. He is definitely one of my favorites.

I've had one going on two years. I use to feed him /her with a tweezers. But I have several angels that rule the tank now so he/she had become a scavenger.

I can't keep any small shrimp or crabs as they become lunch. I have two fire cleaner shrimp with him / her now, these are left alone.

I had a pair of harlequins but they unfortunately became a shrimp dinner in front of my eyes. If they could escape they would but when they molted they became a food source.

Like others have said one of my most favorite fish.
 
I dont have one yet, but will be getting one soon.

I currently have two Snowflake moray eels.

Are GDM as blind as Snowflakes seem to be? My two snowflakes both seem to be very blind.
 
I have a small eel (the brackish water type) in my tank and I absolutely love him. Hes always stalking my damsel trying to get a bite and goes insane when i feed him. Thinking of adding a cleaner shrimp but dont wanna pay $20 for his lunch...
 
Note on when you say "when I feel he's had enough to eat" part. From what I've read about eels, usually, you feed them to satiation 2-3x a week, not how much you think he needs to eat per feeding. Also, there's a DIY mesh screen thread around here, with 1/4" netting attached to aluminum bars that I think would be good for the tank (I saw it on BRS, which mentioned the thread came from RC).

Golden eels sound awesome from what you say about them. Are they a common fish to find? I've been looking every once in a while (not a top fish for me...), but I have yet to find one.
 
Mine is really shy, I can't get him to eat hardly anything. But he does not try to escape. He is rather lazy. I put a firefish in a few weeks ago and then it disappeared. Do t know the outcome. Maybe firefish are on the definite no no list if you are keeping gdm's. Mine also is not an escape artist, he is perfectly content to stay in his hole. I got really lucky when I got a box of Marco rocks in because one of them was tailor made for an eel. See the picture below. That
Hole came like that, I didn't chisel it out. I was hoping when I put it in the tank that he would like it, and sure enough he won't leave the rock.

I had one for about a month before he jumped out of the tank. I have glass tops and he managed to push open the back plastic flaps and slither right out. I was very sad. I'd like to try one again but I'm not sure if my tops will keep the beast in the tank.
 
This is the most recent thread I can find with some who gotone of those i have been looking for over a year.... where the heck did u find out and how much did u pay?
 
I kept one in a mixed reef with multiple small fish (clowns, small wrasses, basslets, etc.). He never bothered fish or coral. He was by far the most personable and interesting fish in my setup.

I fed him 2-3 times a week. I would feed him small chunks of squid from the local market.

I had him about 6 months before I found him underneath my couch one morning. Very very frustrating day...I had a screen too on my tank and he still found a way out. So make sure your tank is covered well!

I got mine from one of RC's sponsors. I'm actually local to Reefwise. When I got mine last summer I paid $150. They often have pairs as well for around $300 I believe.
