KoiQuanta Pricing: Hobby and Pro Plans Explained

By KoiQuanta Editorial Team|Updated Mar 2026

KoiControl users paying $25-40/year still need spreadsheets -- KoiQuanta replaces all of them. That's not a claim about KoiQuanta features overview on a comparison chart; it's about the actual workflow of managing a koi pond or koi business. A tracker that doesn't do dose calculations, doesn't connect your water parameter history to your disease events, and doesn't generate quarantine certificates requires spreadsheets to fill the gaps. KoiQuanta was built so you don't need them.

Here's a straightforward breakdown of what each plan costs and what you get.

TL;DR

The hobby plan is $8 per month per pond and covers full water parameter logging, fish health records, disease identification, treatment dose calculators, and quarantine management.
The pro breeder plan at $29 per month adds multi-pond management for up to 5 ponds, spawning event tracking, and growth comparison tools.
The pro dealer plan at $79 per month is purpose-built for compliance with USDA APHIS import documentation, customer-facing quarantine certificate generation, and unlimited multi-pond management.
One avoided disease loss typically pays for several years of the hobby plan.
Dealers with documented quarantine programs consistently sell fish at higher prices than undocumented competitors, often recovering the annual plan cost through a small number of sales.
All plans include mobile and web access, automatic data backup, and customer support with no hidden fees.

Hobby Plan: $8/Month Per Pond

The hobby plan is designed for individual pond owners managing one pond (add additional ponds for an additional fee per pond).

What's included:

Full water parameter logging with automated charting and trend analysis
Feeding log with temperature-linked guidance and parameter correlation
Fish health records with individual profiles, photos, and observation history
Disease identification module with AI-assisted diagnosis
Treatment protocols with dose calculators for your pond volume
Quarantine management with the 30-day protocol
Seasonal management alerts (temperature-triggered feeding stops, spring startup, winter preparation)
Water change reminders based on nitrate trends
Alert system for parameters approaching thresholds

Who it's for: Hobbyists with one or two ponds who want to replace scattered notes and spreadsheets with a system that actually helps manage health outcomes, not just record them.

Is it worth it? One avoided disease loss in a year pays for several years of the hobby plan. The value calculation isn't about the features list -- it's about how much your fish are worth and how much better your outcomes are with active monitoring versus passive observation.

Pro Dealer Plan: $79/Month

The dealer plan is purpose-built for compliance documentation, import workflows, and customer-facing documentation that hobbyist plans don't provide.

Dealer-exclusive features:

Multi-pond management (unlimited ponds in the plan)
Import documentation module aligned with USDA APHIS requirements
Customer-facing quarantine certificate generation
Quarantine batch management with lot-level tracking
Fish inventory management with health record linkage
Sale record system linking buyer information to fish health history
Export-ready records for regulatory inspection
Veterinary endorsement workflow for health certificates
Customer care sheet generation from fish records

KoiControl has no dealer-specific compliance tools -- one plan for all users, none of the import or compliance features that dealers actually need. KoiQuanta's dealer plan is purpose-built for the workflows that differentiate a professional koi business from a hobbyist.

Who it's for: Koi dealers who import fish and need USDA documentation, dealers who want to generate quarantine certificates that build customer trust, and anyone managing multiple holding systems who needs consolidated oversight.

Pro Breeder Plan: $29/Month

The breeder plan sits between hobby and dealer, designed for serious hobbyists running breeding programs or keepers with multiple ponds who don't need the full compliance documentation suite.

What's added over hobby:

Multi-pond management (up to 5 ponds)
Spawning event tracking and fry management
Breeding program records with bloodline documentation
Show results logging integrated with fish profiles
Growth tracking with photo comparison across seasons

Who it's for: Serious hobbyists running their own breeding program, keepers with several specialized ponds (main pond, quarantine, spawning, grow-out), and people whose collection has grown to the point where a single-pond hobby plan doesn't reflect their management complexity.

Is the KoiQuanta Dealer Plan Worth It for a Small Dealer?

The dealer plan pays for itself in a few ways:

Reduced compliance risk: The cost of a single USDA compliance issue -- fines, legal fees, or fish destruction orders -- vastly exceeds the annual plan cost. Having records that satisfy inspection on demand eliminates that risk.

Higher average sale price: Dealers with documented quarantine programs sell at premium prices. If quarantine certification allows you to price fish 10-15% higher than undocumented competitors, a modest volume of sales recovers the annual plan cost quickly.

Customer service efficiency: Time spent searching paper files for health records, generating manual certificates, and responding to questions that documented records would answer instantly has a real cost. The dealer plan reduces administrative overhead enough to meaningfully affect your time.

Frequently Asked Questions

How much does KoiQuanta cost?

The hobby plan is $8 per month per pond. The pro breeder plan for multiple ponds and breeding tracking is $29 per month. The pro dealer plan with import compliance documentation, customer certificate generation, and multi-pond management is $79 per month. All plans include full mobile and web access with automatic data backup. Pricing is transparent with no setup fees or hidden costs.

What is included in the KoiQuanta hobby plan?

The hobby plan includes: full water parameter logging with automated trend charts and threshold alerts, fish health records with individual profiles and photos, feeding log with temperature-linked guidance, disease identification with AI-assisted diagnosis, treatment protocols with dose calculators, quarantine management with the full 30-day protocol, seasonal management alerts, and water change reminders based on nitrate tracking. It covers everything an individual pond owner needs to manage pond health proactively rather than reactively.

Is the KoiQuanta dealer plan worth it for a small dealer?

For any dealer handling imported fish, yes -- primarily because of compliance risk reduction and documentation quality rather than convenience features. USDA compliance requirements for koi importers create real legal exposure when records can't be produced on demand. The dealer plan's import documentation module aligns with USDA APHIS requirements and generates inspection-ready records. The customer certificate generation also supports premium pricing -- dealers with documented quarantine programs consistently sell at higher prices than undocumented competitors, which offsets the plan cost quickly.

Can I upgrade from a hobby plan to a dealer plan later?

Yes. KoiQuanta plans can be upgraded at any time and your data carries forward to the new plan tier. If you start with a hobby plan and your operation grows to the point where dealer documentation and multi-pond management are needed, upgrading preserves your entire existing parameter log, fish health records, and treatment history in the new plan.

Is there a free trial for KoiQuanta?

Check the KoiQuanta website for current trial availability. Many subscription software products offer a trial period so you can evaluate the interface and features before committing. The pricing page and signup flow will show the current trial terms.

Does KoiQuanta charge per fish or per pond?

The hobby plan is priced per pond, not per fish. You can have as many individual fish profiles within a pond as you need. The pro breeder plan covers up to 5 ponds and the dealer plan covers unlimited ponds, both without additional per-pond fees within those tiers.
