The Problem

Most fish don't die suddenly.
They suffer slowly while their owner
doesn't notice the signs.

01

Your water test app doesn't know when you last did a water change

Every aquarium app logs your parameters. None of them connect those parameters to your maintenance history. So when your nitrate is high โ€” they show you the number but can't tell you why.

02

Generic AI gives generic answers regardless of your tank

Ask any AI assistant why your nitrate is high and you get the same answer every time โ€” regardless of your tank size, your stocking, your filter or how long it's been since your last water change.

03

Nobody warns you before the ammonia spike kills your fish

Ammonia spikes don't happen overnight. The warning signs build over weeks. Without something watching your complete history โ€” you only notice when it's too late.

๐Ÿ  Real AquaBuddy response โ€” Mbuna Tank
Why is my nitrate high?
Your Mbuna Tank (180L) โ€” nitrate is at 50ppm because waste is building up faster than it's being removed.

Your last water change was 16 days ago (25%) and filter clean was 45 days ago โ€” both overdue for a heavily stocked cichlid tank.
๐Ÿ’ง To bring nitrate from 50ppm down to 10ppm in your 180L tank โ†’ 80% water change = 144 litres

No other aquarium app gives this answer. Not one.

Why AquaBuddyAI

What to Look For in an Aquarium AI App

Not all aquarium apps are equal. Here's what separates a genuinely useful tool from a generic one.

01

Does it actually know YOUR tank?

Generic AI gives generic answers. A proper aquarium assistant remembers your specific fish, your filter, your water history and your maintenance โ€” and uses all of it in every response.

02

Does it tell you WHY โ€” not just WHAT?

Showing you a high nitrate reading is easy. Explaining that it's high because your last water change was 16 days ago and calculating exactly how many litres to change โ€” that's intelligence.

03

Can it read your test results from a photo?

Manually entering water parameters is error-prone and tedious. AquaBuddyAI uses AI vision to read your test kit photo directly โ€” saving time and removing human error.

04

Is it built by someone who keeps fish?

There's a significant difference between an app built by a tech company and one built by a hobbyist who actually keeps Mbuna cichlids and loses sleep over water parameters.

Our Story

Built by a Hobbyist.
For Hobbyists.

๐Ÿ 

Gary Haughton

Founder, AquaBuddyAI
Mbuna cichlid keeper, Manchester

Zero coding experience โ†’ Category-leading iOS app in 6 months
"I built the tool I always wished existed โ€” because nobody else was going to do it the right way."

Gary has been keeping Mbuna cichlids for years โ€” fascinated by their behaviour, their colours and the complexity of replicating their natural habitat. Like most serious hobbyists, he spent countless hours searching for good advice and found the same problem everywhere: generic, impersonal answers that knew nothing about his specific tank.

After a serious health scare that forced him to step back from work, Gary found himself with time on his hands and a question that wouldn't leave him alone: why doesn't a proper AI aquarium assistant exist? One that actually knows your tank, remembers your fish, reads your test kits and gives you advice that's relevant to your specific situation?

Having not used a computer since 1998, he taught himself everything from scratch โ€” APIs, code, terminal, database architecture, AI integration. AquaBuddyAI is the result. It's not a corporate product. There's no team of product managers or venture capital behind it. It's one fish keeper who wanted better tools, and who built them.

Frequently Asked Questions

Does AquaBuddyAI read API and Tetra water test kits?

Yes. AquaBuddyAI features a Smart Water Lab with approved kit badges. The AI camera scanner analyses your test strips for API, Tetra and JBL tracking pH, Ammonia and Nitrates without manual entry.

What is an Aquarium Tank Score?

The Tank Score is a dynamic health grade for your ecosystem. The AI evaluates your bioload, hardware runtimes and parameter history into a single score telling you how to fix issues before they threaten your livestock.

How does the AI remember my specific aquarium setup?

AquaBuddyAI uses persistent RAG memory. Unlike basic chatbots our AI saves your livestock profiles, filtration gear and tank type using your historical data to provide precise customised advice every time.

Can I manage multiple aquariums at the same time?

Absolutely. The multi-tank dashboard lets you view parameters for a tropical freshwater tank, Mbuna cichlid setup or marine reef simultaneously without cross-contaminating your AI tracking history.
