Key West, Florida
Koi, goldfish and tank fish: the Key West picture
Key West is frost-free, with January lows around 66F and August highs above 90F, so there is no cool season to buy extra time. As soon as your pet has died, get them into air conditioning straight away, lay them on a towel, surround them with ice packs wrapped in cloth, and find out if your clinic can hold them while collection is arranged. In a hurricane evacuation, the whole chain can empty out, so plan early.
Key West sits at the far end of the Overseas Highway in Monroe County, roughly 160 miles and several hours' drive from Miami, and that distance shapes pet aftercare here more than anything else. Homes are mostly tightly packed conch cottages, apartments and condos in Old Town and New Town, plus Navy housing. Ask any provider whether cremation happens in the Keys or on the mainland, and how long the ashes take to come back down US 1.
Home burial is common in and around Key West, especially where families have land. For a fish, it's quick and meaningful: plant a water iris, a hosta or a small shrub on top so the spot becomes part of the garden. The one thing to avoid is burying a fish that died of disease close to a pond or stream, where rain can carry anything left in the soil back into the water.
About 24,999 people live in Key West, which makes it the 103rd-largest of the 235 Florida communities we cover.
Nearby, we also have local pages for Homestead (105 miles, a larger centre), Naples (110 miles) and Cutler Bay (115 miles), which can help if your vet or the provider you prefer is based there.

Cremation in Florida: a little context
In Florida, about 72.5%[1] of people are cremated, one of the higher rates around. Where cremation is this normal, pet crematories are usually plentiful and some specialize in small animals. For a fish, that means more choice: private or communal cremation, sometimes water cremation, and keepsakes like glass paperweights or pendants. It also means more providers to compare, which is worth doing, because prices for the smallest weight band vary more than you'd think.
NFDA 2024 Cremation & Burial Report state projections (via Occasional Sage) (2024) is where the Florida figure comes from. It counts people; we use it because attitudes to cremating a pet in Key West tend to follow attitudes to cremation generally.
When the weather sets the pace in Key West
Tank fish feel the heat too. An apartment in Key West with the air conditioning off during a August workday can push aquarium water well above what most tropical fish tolerate. If you come home to a dead fish in a warm tank, remove it, cool the room, check the heater hasn't stuck on and add aeration. Then freeze your fish and decide on aftercare when the tank is safe.
Summer trips are when many Key West pond losses happen. A neighbor feeding the fish in August may not realize that a clogged filter or a skipped top-up can starve the water of oxygen within a day. Before you travel in May, June, July, August, September and October, leave a short note: where the air pump plugs in, what normal looks like and what to do if a fish dies. The request is simple: bag it, freeze it and text you, rather than decide anything on your behalf.
Why a small fish still has a minimum price
In the US, almost every fish falls into the smallest weight band on a cremation price list. CareCredit's guide puts pets up to 30 lb at $45 to $75 for communal cremation and $100 to $175 for private[5]. That minimum exists because running the chamber costs much the same for a goldfish as for a small dog. Home collection, a decorative urn and a glass keepsake all add to the total, so ask any Key West provider for a written figure.
The full price table by size is on our Florida page, and the services page explains what each option includes.

Before you bury, scatter or rehome in Florida
Some fish diseases are taken seriously by governments. Koi herpesvirus, for example, is reportable in a number of countries because it spreads between ponds and fisheries. If a vet suspects a notifiable disease, follow their instructions on disposal, which may mean cremation rather than burial. For everyday losses from age or water problems, the normal rules for Florida, set out below, are all you need.
To find your county or city office in Florida, start with the official Florida local government directory.
The rules that apply across Florida (home burial, scattering and who oversees pet cremation) are summarized on our Florida page. Key West may add its own conditions, so check with the city or county before digging.
What to do when your fish dies in Key West
- Make sure. Watch the gills and fins for a full minute. A fish lying still on the bottom can be chilled, stunned or very weak rather than gone.
- Lift your fish out with a net once you're certain; left in the tank, it will start to spoil the water for the rest.
- Seal it in a bag or tub, press the air out and freeze it. Chill it in the fridge instead if you want a vet to find out why it died.
- Test the water the same day for ammonia, nitrite, pH and temperature, and watch the remaining fish closely.
- Decide by size. A koi or large goldfish suits private cremation; a small tank fish often suits a burial, a planter or communal cremation.
- Call a provider and ask what they'd return once they know how long and heavy it is, then have the total put in writing.
Memorials that suit a fish
Key West is famous for its animals, from the six-toed cats at the Hemingway Home to the chickens that roam the streets. Burial is difficult here, since the island is coral rock with water close beneath and even the city cemetery uses above-ground tombs, so most families choose cremation. A little ash scattered at sea off the island, or a potted bougainvillea on the porch, makes a fitting memorial.

Questions people ask
Which nearby towns can I compare with Key West?
The closest communities we cover are Homestead (about 105 miles), Naples (about 110 miles) and Cutler Bay (about 115 miles). Providers based in those places often serve Key West too. Ask each one for a written total that includes collection, so the distance is priced in.
When is the hardest time of year to arrange a burial in Key West?
There is no frozen-ground season here; average lows stay above freezing all year. The other pressure point is August, when highs around 91°F mean a body needs cooling and collecting quickly.
Why does the Key West page quote a human cremation rate?
Because it is the best local signal we have. NFDA 2024 Cremation & Burial Report state projections (via Occasional Sage) (2024) reports about 72.5%[1] of Florida residents are cremated. There is no official pet equivalent, and inventing one would be worse than quoting a real, clearly labelled number.
How much ash does a fish leave after cremation?
Cremated remains usually weigh about 3 to 5% of body weight, and fish tend toward the low end because they're mostly water with fine bones. A large koi might return a few ounces, enough for a small urn. A pond goldfish may leave a keepsake vial's worth. A small tank fish may leave nothing you could collect separately.
What should I do with the other fish after one dies?
Remove the dead fish quickly, then test the water for ammonia, nitrite, pH and temperature. Check the filter, pump and heater. If readings are off, do a partial water change and hold off feeding for a day. Watch the others closely for a week. If more fish look unwell, a vet who sees fish can examine a freshly chilled body.
How do I find someone who will cremate a fish near Key West?
Start with your vet, who will know which crematory handles their small animals. Then call that crematory directly and ask whether it accepts fish. A local fish store or koi club may know who other keepers use. You can also send us your location and we'll email options that serve Key West.
