In the grand scheme of things many fish have a relatively short lifespan and as sad as it is eventually we will be faced with the loss of our dear little pet. For todays article I’m going to discuss appropriate means to dispose of the body. For many hobbyists, the loss of a fish brings up a variety of emotions including grief and frustration. In my opinion these emotions are valid and important to discuss but are better addressed in a separate article which I will cover shortly. For now, I’m going to focus on just the removal of the animal.

When you suspect your fish has died you want to be sure is that he is truly gone. Breathing often becomes quite labored so give yourself a moment to observe him closely making sure the gills or mouth aren’t moving at all. Never dispose of a live fish. If your fish is sick but still alive then you should consider treatment or euthanization. For assistance making that decision read: Euthanizing Aquarium Fish on main Nippyfish.net website. A common myth about fish is that when they die they go “belly up” and float along the water’s surface. This can occur due to gas build up within the body but more often the fish will fall to the tank bottom or become attached to the filter intake. If the latter is the case, unplug the filter to remove the body. If you use a net to remove the fish keep it separate from other equipment and don’t use it in other aquariums until it has been sanitized. This is particularly important if your fish died from a communicable disease like a bacterial infection, virus or parasite. Nets can either be boiled (watch for melting plastic) or cleaned in a diluted bleach solution and rinsed and dried well.

Most people believe that flushing is the simplest and most acceptable method for fish disposal. After all, who hasn’t seen that episode of the Cosby Show when Rudy’s Goldfish dies and the whole family attends a toilet bowl service? What the average fish keeper doesn’t realize is that flushing is not only dangerous for the environment but it is illegal. That’s right, flushing a fish down the toilet risks introducing potential pathogens into the watershed and is a major no-no in the hobby. Of course the risk of being caught is very low but as aquarists it is our duty to act responsibly and to protect the very waterways that support the plants and animals we hold dear. Bottom line, never flush a fish.

The other major option you want to avoid is feeding your dead fish to a larger fish. While this is a common and acceptable method for culling deformed or unneeded fish, it is not recommended for fish that have contracted a disease or have already died. You don’t want to risk infecting healthy animals.

Depending on your personal views of death there are other options. For many, myself included, throwing the fish away with the trash is a safer and simple alternative to flushing. It seems harsh, and I admit I felt a little strange about it the first few times, but ultimately I became comfortable with this method. It’s best for those who subscribe to the ideology that this is just a body and the sweet little fishy personality that wiggled at the glass for me everyday is no longer present but swimming happily in the big pond in the sky.

If you have a composting area at your home this is also a viable option. This way the nutrients from your fish make their way back into the land. It’s a circle of life thing and brings peace of mind to a lot of people.

Similarly, backyard burials are also very common with fish hobbyists. This is obviously a little more time consuming but is often the most emotionally sensitive method and incorporates that “back to the earth” ideology. This can also be a good tool for parents to use to discuss death with their children, though let me be clear that I know plenty of fish parents who bury their fish as much for their own sense of closure. What a lot of mammal lovers don’t understand is that many fish become part of the family as much as any dog or cat. If you are going to bury your fish do it in a part of the yard unlikely to be disturbed later and far away from waterways including ponds, lakes, streams and rivers. Dig a hole at least 2 feet (60 cm) deep, deeper for large fish, and compact well. Dogs, raccoons and other animals have very sensitive noses and you don’t want want them to dig up little Finny in the middle of the night. If you want to wrap the fish in something, I suggest newspaper, cheese cloth or other easily biodegradable materials.

I realize, of course, that people handle the death of their fish differently. Some feel very real grief while others take it as an unfortunate part of the hobby. However you feel about it, remember that fish keepers have a responsibility to each other and our Earth, maybe even more so than most because so many of our actions effect it directly. Please consider these alternatives to flushing the next time you are faced with the loss of your aquarium fish.

    Thank you.
    I have two bettas, and they aren’t dead yet, but I do NOT want to flush them.
    Instead, I’ll probably bury them or throw them away.
    I do dread that day though. I truly do. I can’t imagine life without my two little babies looking up at me.

    I love beta fish! Thanks for posting this! My beta just died, and i only had him for a week. I got a new one a while ago named Omaree, and he’s totally healthy.
    I just changed his bowl to a bigger one, and he’s been jumpy ever since. He always hides from me, and never used to. He isn’t eating as much a as he used too. Do you think he is just adjusting, or sick? I don’t think he’s sick, and i am hoping he’s gonna get over it.
    He also snt as active, and sleeps ALOT.
    I also wil HATE the day when my little beta passes. 🙁
    But for now i still have my baby, and he loves his Mommy! 🙂

    Thank you for this post. My male Betta Squish just died half an hour ago and I feel like I just lost my best friend. I had Squish for 2 1/2 years and sadly he succumbed to Columnaris today (what a horrible thing to witness). Thanks to this page I now know how to give my beloved friend a safe and proper send off.

    My Betta fish, Finnegan (Finn for short) passed away this morning. He lived with me for 4 years and 3 months. Amazing! I am so sad! I never thought I would cry over a fish. I am going to buy a “Bleeding Heart” plant and bury him with it. Thank you for you for sensitive and respectful blog.

    I just lost my betta Samuri this morning): Last night, she was straight up in down with her head to the surface and when i changed her water, she didn’t squirm as much… When i put her in the other bowl to clean out hers, she started jolting around. then she settled at he bottom when i put her back in her bowl and she sort of layed her tail on the bottom and put her head up. like this——>http://www.wetwebmedia.com/Anabantoids/Bettas/P1010161b%5B1%5D%20sick%20betta.JPG
    SHe didn’t move alot…and i wasn’t going to be surprised if she was dead this morning because i knew something was wrong. I first got her from my friend a while back…it was towards the end of the summer…until today. she was in a big tank with a dalmation molly, two glofish, and a red finned tetra…she never fought or did anything harmful to the other fish when my friend owned them. when we moved to my house, she started biting the other fishes fins. Samuri just changed. It wasn’t like before so i had to move her to a seperate bowl. :ike i said, she died this morning and thanks to this article…even with some tears that came with it…i know that i will bury her in the backyard. ),:
    this is the second pet i have experienced death with. when i was little, my cat died and we buried him in the backyard, then we moved………..
    Im so sorry I let you die Samuri…I love you and you will always be in my heart. May you rest in peace. I hope you meet more fishies like you! Goodbye),:

    much to my dismay.
    i will miss him all the time
    my sweet little pretty boy – so sublime!!!

    This article is still helping. My little Ariel just succumbed to dropsy and that was hard to watch. She passed at her sitter’s house while I was away on a work trip. Thank you for the post Nippy Fish. Thank you Ariel for being my first fish. I miss you, you little goober.

  14. Betta Mother says:

    Many people have told me that I shouldnt be a mother and that I cant take care of anything. And I believed them, so I got a Betta fish – the easiest fish to care for – to prove to myself that I could take care of something. I spent hundreds of dollars and tried everything to keep it alive, but it refused to eat and died last night. I’m going to bury it in the backyard along with any hope I had of being a caretaker and a mother.

    Thank you for the article, when my friends and family point out how pathetic I look burying a fish I’ll be able to pull this out and tell them it is the most environmentally friendly option.

  15. Angie says:

    Couldn’t you flush a fish if you have a septic tank? The fish would be making its way to the backyard, not a watershed.

  16. Kai says:

    My betta died today so I put him in a plastic container that’s small and buried him in a huge planter that of own.

  17. Ivana says:

    Thank you so much for this article! I REFUSE to flush my betta. He isn’t dead but his colors are fading which I think is an indicator of aging. ie had him for exactly a year, today.

    • A farmer says:

      That means he was between 2-3 years of age but It also differs about the species like colorful(domesticated) betta fish fish tend to live 3-5 years while wild betas Can live between 5-10 years other even live up to 11-12 years In Some farms in S.E Asia.Never dispose a betta fish Especially the WILD variant it will be Very hard to get rid of Established wild betas Communities and it will Outcompete native fish by eating their Young

  18. A farmer says:

    My betta had lots of babies and when it grow up I was going to sell them but The other betta tend to be ugly so I throw them into Our organic rice Farm (50 hectares) but after a year or two I saw lots of them in a Nearby stream that Goes through a Large lake will they Affect The fisheries in the lake and how to get rid of them we tried Drying the Rice paddies for a month but when we put the water again In just 5 mins there lots of them eating away some Rice Plantings And last month I tried to experiment with it Like putting it into our canal I put 5 of them and they are normal I want to get them out of the canal but it’s gross so I let them there it looks like wild betas seems Thriving in moderately polluted waters like tilapia and janitor fish but It ERADICATED the Pest in our Farm like (Snails,Large worms,an eel,And many other insect) BUT becoming the PEST itselt. how to get rid of them NATURALLY cause this is an Organic farm.
