Lost a fish you loved? Three quick choices to find your next step
Koi can live 30-40 years[1], so losing one can feel like losing a long-time family member. This short quiz helps you choose which question to settle first, whether your fish lived in a pond or a tank.

Fish cremation: choose your next question
Use Fish Cremation & Memorial Services to choose your next fish cremation question, wherever you are worldwide. Select one guide topic, one detail to clarify and your current planning stage.

Which decision would you like to explore first?
Fish Cremation & Memorial Services organizes this worldwide fish cremation selector around four guide topics. Choose the question closest to what you want to understand first. The next two choices identify one detail and your planning stage. You can change the topic later; selecting it does not submit an inquiry or authorize any arrangement.
Inside the quiz
What the quiz asks and why
The first question offers four fish-specific topics: how much ash a fish or koi really leaves, marking a loss beside the pond, biodegradable memorials, and short rituals after an aquarium death. Pick the one that's on your mind. The second asks which detail you'd most like cleared up, such as your fish's species and length, or whether you want ashes back at all. The third asks where you are: reading, weighing preferences, or checking a written offer.
Your result shows the guide for your topic, the detail you chose and a suggested next action. It doesn't rank you or calculate anything behind the scenes, and your answers vanish when you clear them or leave the page.

Turning your result into one clear question
Each stage leads somewhere slightly different. Reading first? Open the linked guide and note what it leaves unanswered for your fish. Holding preferences with gaps? Take the detail you chose into the fish planning worksheet. Already have a quote? Check it against what you actually want back, especially the ash amount, before agreeing.
You can copy your choices or open a ready-written email. The draft opens in your own mail app and only goes anywhere if you press send. If you'd rather have us look into it, the form at the top reaches our team and we reply by email.
The ash question
Will a fish cremation give you ashes back?
Often not much. Remains typically weigh about 3-5% of body weight[2], and fish bones are light and fine. A 2 lb koi might return a spoonful or two; a small tetra may return almost nothing visible. That's why our guide calls fish ash yields "symbolic", and why honest providers will tell you what to expect before you pay for private cremation.

If a keepsake matters, choose one sized for a pinch. A cremation pendant holds only a pinch (at most about a teaspoon)[3]. The symbolic ash yield guide explains which fish sizes are likely to return enough for an urn and which are better suited to a non-ash memorial.
Where to remember them
A marker by the pond or a quiet spot indoors
Pond keepers often want something at the water's edge. Engraved pet garden stones start at about $39[4] from one US retailer. Our estimate across three US sellers puts the median starting price at about the same $39[5], and a flat stone can sit among marginal plants without disturbing the fish that remain. Our pond-side markers guide covers placement, frost and keeping stone dust out of the water.
If you plan to bury or scatter ashes near plants, note that cremated remains are very alkaline, with a pH of about 11.7[6]. A little mixed well into soil is usually fine; a concentrated pile can harm roots. The biodegradable memorials guide suggests gentler options.
Most fish keepers still have other fish to look after: 77%[7] of US fish owners keep two or more. After a loss, test the water, check the survivors for the same symptoms and ask your aquatic vet whether anything should be kept for testing before the body is cremated. A sudden death in a pond is sometimes the first sign of a problem the rest of the fish will face too.

Families
When the fish belonged to a child
A fish is often a child's first experience of death. In an RSPCA survey of bereaved owners, 93.4%[8] of parents wanted better guidance on helping children through pet loss. A short ritual helps: a drawing taped to the tank, a few words, a stone the child chooses. The aquarium loss rituals guide has ideas that take ten minutes or less.
Let children see that it's normal to feel sad about a fish. Adults sometimes brush it off, and many owners hear that: 34.5%[9] of bereaved pet owners in one UK survey were told "it's just a pet".
What to avoid
Why flushing or releasing isn't the kind option
Flushing a dead fish can spread disease into waterways (here's why), and releasing an unwanted live one is worse. Goldfish can grow far bigger than people expect: they typically live 6-7 years[10], and in the wild some approach 2 feet long. Minnesota's natural resources agency says to never release[11] goldfish, and suggests rehoming instead. In the US, the Habitattitude campaign, run with the US Fish and Wildlife Service and NOAA, lists other alternatives to releasing aquarium pets.
If you're not ready to decide, the aftercare options comparison sets out cremation, burial and other choices side by side, and our services page explains what we can help arrange.

Questions people ask
Can you cremate a goldfish or betta?
Yes, some pet crematories accept very small fish, usually for private or communal cremation. Be prepared for very little or no visible ash from a small fish. Ask the provider what they expect to return before you choose a private option or buy a keepsake.
What should I do with my fish's body right now?
Remove it from the water promptly so it doesn't affect water quality for other fish. Wrap it in a paper towel, place it in a sealed bag and keep it in the fridge for a day or two, or the freezer if you need longer to decide.
Does the fish aftercare quiz save or send my answers?
No. The quiz keeps your three choices in the open page only. They leave your device only if you copy them or send the email draft yourself. Clearing the quiz or reloading the page deletes them.
How much does it cost to cremate a koi?
Prices vary with size and provider. PetMD puts US private cremation from about $100[12], and a large koi usually falls in the smallest price band because of its weight. Ask whether collection, a container and delivery are included.
Is it okay to bury a fish in a potted plant?
Many people do, and it's a gentle option for a small fish. Bury it deep enough that pets won't dig it up, and avoid edible plants. If you're burying ashes rather than the body, mix them well into the soil because of their high pH.
