Memorial ideas that actually suit a fish
The most fitting fish memorials often need no ashes at all: a gyotaku ink print, a water lily planted in their name, a painted stone or a photo by the tank. If your koi or large goldfish was cremated, a pendant or glass keepsake needs only a pinch.

The short answer
What makes a good memorial for a fish?
A good fish memorial matches two things: how big your fish was and where it lived. Tiny aquarium fish leave little or nothing to collect after cremation, so the kindest tributes for them don't depend on ashes. A mature koi is different, and can return enough for an urn, a scattering and a piece of jewelry.
Cremated remains usually weigh around 3-5% of body weight[1]. A betta weighs a few grams, so that works out to a fraction of a gram, often not enough to keep separately. Our guide to symbolic ash yields for fish and koi explains this in detail. So start with the ideas below that suit your fish, then decide whether cremation adds anything for you.

For any fish, however small
Which fish memorials need no ashes at all?
These work for a guppy as well as a prize koi, and several cost almost nothing.
- A gyotaku print. Gyotaku is the Japanese art of printing a fish with ink on paper. A gentle print of your fish's shape, made soon after death with non-toxic ink and thin rice paper, captures scales and fins in a way no photo does. Rinse your fish afterward, and tell the crematory if you've done it. Skip this if a vet needs to examine the body.
- A photo or painting. Choose a picture of your fish in motion, not a still one. Many local artists paint pet portraits from photos, and koi make striking subjects.
- A water lily in their name. Plant a hardy lily in your pond, or a small tropical one in a patio tub. Each bloom is a quiet reminder, and it gives the fish still with you shade.
- A tank ornament. A small ceramic or stone piece, placed where your fish liked to rest, keeps them part of the aquarium. Pick aquarium-safe materials so the water chemistry isn't affected.
- A named pond feature. Name a new waterfall, a flat basking rock or a bench by the pond after your fish.
- A donation. A gift to a public aquarium, a freshwater conservation group or your local koi club's education fund turns the loss into something useful.
For pond keepers
What are some memorial ideas specific to koi?
Koi are often kept for decades, as Japan's koi promotion association notes of their lifespans, and known by name, pattern and personality. Memorials that sit in or beside the pond tend to feel right, because that's where you spent time with them.
- An engraved pond-side stone. Engraved garden stones start from $38.95[2] at one large US retailer, and natural-stone memorials run $38–$115[3] depending on size. Our estimate across three US sellers puts the median starting price for engraved garden stones at about $39[4]. See our guide to pond-side markers after koi loss for placement and materials.
- A pattern record. Keepers often photograph koi from above. Print that overhead shot, which shows the pattern most clearly, and frame it with the fish's variety, age and where it came from.
- A club tribute. Many koi clubs share members' losses in newsletters or at meetings. Writing a short note about your fish's history can be a good way to mark it among people who understand.
- A new fish of the same variety, later. Some keepers eventually choose a young koi of the same variety as a living tribute. Only when you're ready, and never as a stand-in.
If your fish was cremated
What can you make with just a pinch of ashes?
If your fish was large enough to leave collectible ashes, a lot of keepsakes need far less than you'd think. That makes them a good fit for fish, where the total is usually small. For jewelry, by our estimate a typical sterling silver ashes pendant costs about $130 to $240[5], with stainless steel far cheaper.
| Keepsake | Ash needed | Typical price |
|---|---|---|
| Ashes pendant or urn necklace | a pinch (at most about a teaspoon)[6] | Cremation jewelry typically $30–$300+[7] |
| Ashes-in-glass piece (paperweight, bead, heart) | 1/8–1/2 tsp[8] | UK example: glass pendant £170, paperweight £195-£240 [9] |
| Keepsake or mini urn | A small portion | $15–$60[10]; a single keepsake around $28 [11] |
Glass studios work to their own timelines, typically 2–8 weeks[12] after they receive the ashes, so allow for that if you're planning a gift or an anniversary. Always ask the maker how much ash they need before you send anything, and keep a little back in case a piece needs remaking.

What if your fish was too small to leave any ashes?
It's worth being clear-eyed here. A very small fish may leave nothing that can be gathered apart from the chamber, and an honest provider will say so before you pay. Some offer a symbolic return with a certificate; others will gently suggest another path. Neither choice is wrong.
For small fish, the no-ash ideas above usually feel more personal. You might also choose a plantable memorial: a small burial in a large pot with a new plant, or a biodegradable keepsake. Our article on how to bury a pet fish covers depth and planters. Our guide to bio memorials after fish loss covers those, and if you'd like a short family goodbye to go with it, see our page on short rituals after an aquarium companion dies.
Children's first pet
Which fish memorial ideas work well for kids?
For many children a fish is the first pet they've looked after, so a memorial they make with their own hands matters more than anything you could buy. Let them lead and keep it simple.
- Paint a smooth stone with the fish's colors and name, then seal it with outdoor varnish.
- Draw or write a letter to bury with a small fish, or to keep in a memory box.
- Make a simple gyotaku-style print with a rubber fish stamp or a toy fish, so they learn the idea without handling the body.
- Choose a plant together and give it the fish's name.
- Make a paper fish for every year, or every month, they had together.
If your child is struggling, our article on grief after losing a fish has plain-language ways to talk it through, and free lines such as Tufts University's Pet Loss Support Helpline are open to adults supporting a grieving child.
Budget
How much do fish memorials cost, from free to keepsake?
A fish memorial can cost nothing at all or run into the hundreds. Roughly, the options fall into three bands:
- Free or nearly free: a painted stone, a photo print, a child's drawing, a named pond feature, a gyotaku print with craft-store ink.
- Modest: a water lily or new plant, a keepsake urn, an engraved garden stone, a small donation.
- Larger: glass art or jewelry made with ashes, a commissioned painting, a carved natural-stone marker.
If you're considering cremation mostly for a keepsake, add that cost to the picture. The services page explains what cremation looks like for fish of different sizes, and the budget planner below helps you set a comfortable total before you shop.

Questions people ask
What is a gyotaku print of a pet fish?
Gyotaku is a traditional Japanese technique where ink is brushed onto a fish and paper is pressed over it, recording its exact shape, fins and scale pattern. Some keepers make one of a much-loved fish as a lasting portrait. Use non-toxic ink, work gently, and rinse the fish afterward if you plan cremation or burial.
Can I plant something in memory of my fish if I have no pond?
Yes. A small water lily grows happily in a watertight patio tub or large glazed pot, and a hardy houseplant or garden shrub works just as well. Some families bury a small fish in a big planter and grow a flower on top. Choose something you'll enjoy looking after, since caring for it becomes part of the memory.
How much ash do I need for cremation jewelry?
Very little. An ashes pendant typically holds only a pinch, at most about a teaspoon, and glass pieces use only about an eighth to half a teaspoon. That means a koi or large goldfish can usually supply a keepsake or two. A very small aquarium fish may not leave enough, so ask the provider what to expect before ordering jewelry.
Is it okay to put a memorial ornament in the tank with my other fish?
Yes, if it's aquarium-safe. Choose items sold for aquariums, or glazed ceramic, glass or inert stone, and rinse them well. Avoid painted garden ornaments, metal and anything with glue or varnish, which can leach into the water. Never place ashes in a tank with living fish.
What can I give a friend whose koi died?
Something that acknowledges the fish by name goes a long way. A card that mentions the koi, a water lily for their pond, a framed photo of the fish, or a donation to a koi club or freshwater conservation charity are all thoughtful. Avoid offering to replace the fish unless they ask.
Do I need to cremate my fish to have a meaningful memorial?
No. Many of the most personal fish memorials, such as prints, paintings, plantings and pond-side stones, don't use ashes at all. Cremation makes the most sense when your fish is large enough to return a meaningful amount and you want something physical to keep, scatter or share.
