My snowflake eel seems to be acting odd. Normally he’s pretty active, but as of now he is just kind of hanging out of the rock he normally lives in, but doesn’t move much. Also seems to be on a hunger strike, hasn’t eaten any of the food I’ve given him the past few days. Ive recently removed all the sand from the tank and changed the rock landscape. I have a video here for reference. I’d take a better close up but I’m currently on bed rest from a knee surgery lol.

Here is the vid
Welcome to Reef2Reef!

The video didn't load (the site struggles with videos; most people upload to a site like YouTube, then link the videos here from there).

A few questions:

-How big is the eel?

-What have you been feeding the eel and how often?

-How long have you had the eel?

-How old is your tank?

-When did you change up the sand and rocks, and when did the eel's hunger strike start?

-Is the eel showing any other odd symptoms (like bloating, for example)?

Dang, I’ll try to figure the video out tomorrow, the eel is about a foot long, I either feed him clams on a half shell, or pieces of shrimp. He tends to eat both but sometime he will stop eating one and I’ll swap over to the other. I’ve had him for about a year or so. My tank is pretty old, I’d say early 2000s but was re-siliconed a while back. I removed all the sand/moved the rocks 4 days ago. He’s been on hunger strike for about a week, sometime he will wrestle with the food but not eat it. It’s hard to tell if he looks bloated, I’d probably say no. As for other symptoms, a while back he was twitching his head to the side every once in a while. I read that it may have been sand in his gills aggravating him, or that he had some sort of infection, I was able to get my hands on the proper medicine for it and that seems to have gone away. Thanks for the reply!

Try some Squid. My snowflake loves it, she gets super excited when she smells it. And what do you mean hanging out of the rock? I have 3 eels. I attached pictures for you to look at and see if thats what you mean by hanging out of the rocks. Cause that could be normal and where he is comfortable.

Agreed - this could be normal behavior; video or pics would help to say for sure.
I either feed him clams on a half shell, or pieces of shrimp. He tends to eat both but sometime he will stop eating one and I’ll swap over to the other.
As mentioned, you can try squid - I've heard some eels tend to really go for squid. Live food (such as live ghost shrimp or fiddler crabs) is also a good, last resort option to try and get it feeding again.

How often do you feed it? Would you say it eats more of the shrimp, more of the clams, or pretty even portions of both?

With regards to the long-term diet, I'd suggest adding a good, fatty fish like salmon (the gold-standard) or mackerel (a good, second place), squid is a good one to add, crabs too if you can do so without breaking the bank, and then I'd also add in some algae (preferably multiple types) to get a few more vitamins and minerals in there that might not be supplied by the meat.

With all the foods, the fresher the better, and the more intact the shrimp is (head, tail, shell, etc.) the better. Ulva, Halymenia, and Nori would be my first suggestions for algae to add, but others like Porphyra and Spirulina would be good too. I doubt the eel would eat the algae by itself, so supplementing it either with algae pellets (such as NLS Marine Fish Pellets), an algal gelatin feed, or through something like wrapping the meat in the algae would be my suggestion.

For more diet suggestions/info, I'd suggest reading through lion king's threads below:
Here's 3 of my most comprehensive threads on feeding lionfish and other predators.

I was able to get my hands on the proper medicine for it and that seems to have gone away.
What medication was it?

Hey thanks for the reply, I’ll try the squid, and maybe grab some full shrimp if I can find it. I never knew they would potentially eat algae, I don’t have any way to get the pellets other than ordering them online(only one salt water fish store in my town) but I’ll look into it.
I usually feed him every 2-3 days.
I’ll try attaching a photo below of what he was doing. The video that I was suppose to upload is pretty much him just not moving in the same spot. As of now he seems to be acting a bit more normal. Usually he just pokes his head out from the rock and looks around or is just deep inside the rock sleeping I’d assume.

The medication I used was mixed in with their food. It was called paracleanse.

I never knew they would potentially eat algae,
Predators typically get their "vegetables" (like algae) from their prey - when they eat the herbivores, they eat the vegetables in the prey's organs too.

So, they may or may not purposefully eat the vegetables, but they often still play an important in predator health/nutrition.
I usually feed him every 2-3 days.
This is probably too often, especially if the eel is larger. Depending on the size, anywhere from once every 3 days to once every 7 days (but more likely 5) may be appropriate.

Ok thanks for the tips, I was able to get some squid picked up, tried it but he still didn’t eat. Guess I’ll just give it a go again tomorrow. I’ll have to look into the algae idea, I could definitely add it into the food I’m already feeding him if I get my hands on some.

Update: been a few days, still hasn’t eaten I don’t believe. He was hiding out in his rock for a while, finally came out for a bit then I found him like this. Breathing fairly heavily and not moving much for the past while. I read up on eels in this state being potentially deficient in nutrients/vitamins, and/or because of high nitrates. My current water is sitting at 1.024 salinity, no ammonia, quite a bit of nitrate that I’m still dealing with, currently doing another water change right now. Other than that had the rest of my levels checked at local aquarium shop, everything came back good.

Hmm. That's not good - eels have been known to go on hunger strikes for a few days/a couple of weeks at a time, but the heavy breathing and not moving much is a bad sign.

Maybe one of the #fishmedic will have some advice for you there.

A couple more photos, he seems to be only breathing out of one of his vents. I tried looking into it but can’t come across anyone having that issue ever before.

Eel died this morning, after a lot of research I’m having a large debate between what could have gone wrong. My guesses based off of other threads compared to how he was acting were either, the nitrates were too high (Nitrates were at 20-25), he had injured his neck from the moving of rocks or having gotten pinched somewhere, he had an internal injury or brain injury, or he wasn’t getting the proper vitamins from his diet of clams and shrimp and/or had grown more of a dependence for certain vitamins he wasn’t getting enough of(thiamine?). I really loved that eel, he was the favourite in my tank for sure! Sad to have lost him, but I appreciate all the help!

Interesting. I know that this may be too late to ask, but incase if you are planning of keeping an eel again here are a few things i wanted to ask and say

Did you quarantine the eel when you first got it?

Did you treat him with copper?

Was the store where you got him from usually treat their tanks with copper?

As for the diet it seems to be lacking in some nutrients

For example: i feed my zebra eel which is also a pebble tooth, whole head shrimp, clams, crabs, squid,

Whenever my other eels go into a hungerstrike, I usually change the type of fish i am feeding them and that tends to work.


It's usually necessary to quarantine new eels and treat them with api general cure since most of them come in with internal parasites and can live many months or even a year (they are really hardy and durable) before they suddenly stop eating and die.

For me, nitrate have never been a problem, and my nitrates do end up to be quite high about 50 to 60 and according to research that never seems to be a problem unless the fish is really delicate and trust me, eels aren't those "delicate fish"

There is definitely a chance that those big rocks could've crushed him but i would say that, that's a low chance since you would of most likely have seen the damage done

As for deficiency, thiamine is a vitamin b1 which is usually found in mussels but more lesser in some fish, some fish contain really high amounts of thiaminase which breaks down thiamine (vitamin b1) hence making the fish really susceptible to thiamine deficiency, this is why it's mostly recommended to feed your fish a variety of foods. One of the fish which are really high in thiaminase is shrimp and hence is recommended not to be used as a stable food.

Copper can really impact an eels life and can definitely do enough damage to the liver in which it can greatly shorten an eels life and most of the eels I've seen or read about have lived only about a year after being treated with copper

These are what I've learned in keeping 4 eels for over the years
