Built for how a pet store really runs
Livestock is not like other stock. It lives in a tank or enclosure, arrives in batches, dies, and sometimes shares water with its neighbours. The records follow that.
A ledger for every tank and enclosure
Every arrival, sale, loss and move is an entry, so counts always add up and nothing goes negative. Open any tank to see exactly how it got to today's number.
Receiving that does the typing
Scan a supplier invoice or import their spreadsheet. Choose where each fish goes, confirm, and print a put-away list grouped by tank so it is easy to do on the floor.
A map of your store
Draw your rooms and drop tanks and enclosures on the floor plan. Click a tank to open it. Overlays show what needs attention at a glance. Optionally share a customer map.
QR labels on every tank and enclosure
Print a label with a code. Staff scan to log or look up a tank or an animal, and customers can scan to see what is in it and whether it is available.
Shared water, handled
Group tanks that run off one sump. Readings and problems on the shared water show on every tank connected to it.
Staff logins that fit
You create logins for your team. Staff can receive, move and sell stock, but never see what you paid for it.
Online orders that hold the right fishEarly access
Connect your Shopify store and see what it says next to what is really in your tanks. Online orders reserve the matching fish and show up on the pick list by tank, so nothing is promised that you do not have.
We keep only the order number and the items, never your customers' names, addresses or contact details.

A Shopify theme for pet stores that sell fish
Breeder Market Pro keeps freshwater and saltwater apart everywhere, and shows what shoppers want to know: size, temperament, tank size and care level. It works on its own, with or without the rest of Breeder Market. Shops can ask us for it at support@breedermarket.com.
Fresh and salt, never mixed
Separate doors on the home page, separate lists, separate carts. A reef customer should never scroll past a goldfish.
Reptile keepers and breeders, too
A reptile is an individual, not a lot. Each animal gets its own record, each enclosure gets limits that you set, and a breeding season is tracked from pairing to hatchling. Breeder Market records what you tell it and points out what crosses your own limits. It never tells you what is right for an animal.
Enclosures, with your own limits
Log warm side, cool side, humidity and UV from your phone and see the trend. You set the limits for each enclosure, and a reading outside them is pointed out in plain words. We don't set targets for your animals.
A record for every animal
Morph, sex and how it was sexed, hatch date, source, your own tag, and whether it is a holdback, a breeder, for sale or held. Photos and notes stay with the animal.
Feeding, weight and shed logs
Log what was offered and whether it was taken, weights with a chart over time, sheds and health notes. You type the prey. Nothing is suggested.
Reminders per animal
Choose how often an animal is fed, weighed or checked. Logging it marks the reminder done, and it drops away when the animal is sold.
Lineage you can print
Link the parents you have records for, or note the ones you don't. See siblings and offspring, and print a three-generation pedigree.
Pairings and breeding events
Record each pairing with its events in your own order: introduced, locked, ovulation, follicles, pre-lay shed, separated.
Clutches and incubation
Count fertile, slug and infertile eggs, note the incubator and the temperature and humidity it was set to, log incubation readings, and record the hatch. Hatchlings can be created as animals linked to the clutch and both parents.
Fertility and hatch rates
See fertility and hatch rates for each pairing and each year, worked out from what you entered.
Genetics oddsEarly access
Record each animal's traits as visual, super, het or possible het, then see what a pairing could produce and how likely each result is. For ball pythons and leopard geckos, with sources for each trait. It never recommends a pairing, and the trait lists have not yet been reviewed by a breeder.
Reptiles use the same QR labels, stock ledger and photos as fish. Pedigrees are compiled from your own records and are not verified.
Listings and buyer recordsComing soon
List an animal straight from its record, including on Shopify, and give a buyer a page with the animal's history.

Questions, answered
The short version of what people ask before they sign up.
What is Breeder Market?
Breeder Market is stock, tank and enclosure software for pet stores, reptile keepers and breeders. It keeps a ledger of every animal from delivery to tank to sale, and gives hobbyists simple logs for their own tanks and enclosures.
Can it track both fish and reptiles?
Yes. Fish live in tanks, with water tests and shared-water groups. Reptiles live in enclosures, each with its own temperature and humidity log, and every reptile has its own record with feeding, weights, sheds, photos and lineage. Both use the same stock ledger, QR labels and photos.
Does it help with reptile breeding?
Yes. You can record pairings and their events, clutches with fertile, slug and infertile counts, incubation settings and readings, and the hatch, and create hatchlings linked to their clutch and both parents. It shows fertility and hatch rates for each pairing and year, and a genetics calculator for ball pythons and leopard geckos shows the odds a pairing could produce. It never recommends a pairing.
Does it work with Shopify?
A Shopify connection is in early access. It reads your products, stock and orders, matches listings to your animals, and holds the matching animals for each order. It keeps only the order number and the items, never your customers' names, addresses or contact details.
Does it tell me what my animals need?
No. For reptile enclosures you set your own temperature and humidity limits, and readings outside them are pointed out in plain words. Breeder Market records what you tell it. It does not set targets or tell you what is right for an animal.
Can my staff see what I paid for stock?
No. Staff logins can receive, move and sell stock, but they never see what the stock cost.
Can I try it before I choose a plan?
Yes. A personal account is free to start, and a shop account begins with a trial, so you can add your first tank or enclosure and see how it fits before choosing a plan.
Start with one tank or enclosure, or the whole store
Create an account and add your first tank or enclosure in a few minutes.
