BUILT BY AQUARISTS, FOR AQUARISTS
Aquariums deserve better tools than spreadsheets.
The aquarium platform built for serious hobbyists — track parameters, schedule maintenance, predict breeding outcomes, and connect your gear.
We'll email you once when Blissfish is ready. No pressure to buy. No spam.
Everything serious aquarists actually need.
Twelve tools that replace ten apps.
Parameter Tracking
Log readings in seconds, not minutes.
Thumb-friendly number pad. Custom parameters per tank. Per-tank alert thresholds. Works offline and syncs when you're back.
Liquid Test Reader
Photograph your API tube. Get the reading.
Built around the kits serious aquarists actually use — API, Salifert, Red Sea, Tropic Marin. Pick your brand once, then just snap and log.
Strip Scanner
A quick-check option for daily glances.
Snap a photo of your test strip and the app fills in the reading. Strips are inherently variable — we recommend liquid tests for breeding and reef work.
Maintenance Scheduling
Never forget a water change again.
Recurring tasks per tank — water changes, filter cleans, glass scrapes — with reminders that respect your routine. Full history per tank.
Drift Watch
Catch slow problems before they become emergencies.
Trend detection flags slow parameter creep — pH decline, KH falling, nitrate climbing — the kind of drift you miss because you only check once a week.
Breeding & Genetics
For breeders who need more than a notebook.
Lineage trees, spawn logs, and trait tracking for shrimp, bettas, guppies, clownfish, discus, killifish, cichlids, and more. Cross Predictor live for Caridina and Neocaridina, in beta for bettas, guppies, and clownfish morphs. Inbreeding alerts across any line.

Built for breeders, not just keepers.
Whatever you breed, Blissfish has tools for it. Some species get deep genetic prediction. All species get serious lineage tracking.
Caridina cantonensis
Caridina Shrimp
Cross Predictor live. Crystal Red, Crystal Black, Taiwan Bee, and related lines. Built around how serious Caridina keepers actually work.
Neocaridina davidi
Neocaridina Shrimp
Cross Predictor live. Cherry, Yellow, Blue Dream, Green Jade, Bloody Mary, and all neocaridina davidi color forms.
Betta splendens
Betta
Tail types (HM, HMPK, CT, DT) and major color genes — cambodian, marble, dragon, koi. Predicted with rule-based Mendelian logic. Polygenic traits noted, not guaranteed.
Poecilia reticulata
Guppy
Snakeskin, tuxedo, half-black, mosaic, cobra, and full red strains. Sex-linked trait math (cobra is Y-linked) handled correctly. Polygenic modifiers noted.
Amphiprion ocellaris
Clownfish (Designer Morphs)
Picasso, Snowflake, Black Storm, Mocha, Frostbite, Wyoming White, DaVinci. Based on published breeder data from ORA, Sustainable Aquatics, and others.
Symphysodon spp.
Discus
Pedigree tracking for established strains — pigeon blood, snakeskin, leopard, blue diamond. No prediction (Discus genetics are too polygenic to model), but pedigree matters for value.
Nothobranchius spp.
Killifish
Strain preservation focus. KCF code support, location strain documentation, generational tracking. Hybridization warnings keep your lines clean.
Apistogramma spp.
Cichlid
Apistogramma, peacock cichlids, Tropheus, Tanganyikan species. Location variant tracking, F1-wild documentation, selected line breeding logs.
Other species
Plecos, Corydoras, rainbowfish, goldfish, koi, and anything else. Spawn logs, lineage, and grading work for any breeder.
Honest about what's predicted: Live = fully tested punnett-square logic. Beta = rule-based predictions for well-documented traits, still gathering feedback. Lineage only = strain preservation and pedigree, no prediction (because the genetics aren't tractable, not because we're lazy).
Whoever you are in this hobby, you'll find your view.
The Reefer
Parameter tracking, dosing logs, equipment management, maintenance scheduling — plus live data from Apex or Focustronic. Built for mixed reefs and the people who run them.
The Aquascaper
Tank Journal, photo timelines, plant tracking, maintenance scheduling. Document every iteration of your scape and look back on the journey.
The Shrimp Breeder
Precision parameter tracking (TDS, KH, GH), breeding genetics, lineage trees, Cross Predictor, and grading tools. Built around how Caridina keepers actually work.
The Multi-Tank Hobbyist
Cross-tank dashboards, smart tags, custom views, and shared access. Whether you keep 3 tanks or 30, Blissfish scales with you.
The Shop, Breeder, or Club
Fish stores, breeding operations, clubs, and serious multi-tank operations. Multi-user access, inventory mode, bulk operations, custom branding. Blissfish Studio is built for you.
Studio — for shops, breeders, and serious operations.
When 5 tanks isn't enough. Built for fish stores, breeding operations, aquarium clubs, and anyone whose tank count outgrew their spreadsheet.
Multi-user access
Up to 5 seats per workspace. Owner, manager, logger, viewer roles. Know who logged what, when. Perfect for shop staff or breeding partners.
Inventory mode
Track livestock counts, retail pricing, and sales per tank. Built for fish stores — record stock, log sales, see real revenue per tank, all in one place.
Your brand, your dashboard
Upload your logo, set your brand color. Your workspace dashboard wears your colors — useful for shops showing the dashboard to customers, or breeders presenting to buyers.
Plus bulk operations, priority support, unlimited tanks.
Get Studio — $29/monthPricing that doesn't punish you for taking it seriously.

Built because every other option is broken.
The 2012 app problem
Aquarimate works, but looks ten years old and can't keep up with modern reefkeeping.
The spreadsheet problem
When the best aquarist tools are a Google Sheet and a notebook, the bar is on the floor.
The forgetting problem
Parameters drift. Maintenance slips. Fish die from problems you would have caught if you'd been looking.
“I'm shocked by how bad the options are.”
Michaela, founder — Westlake Village, CA
Why Blissfish exists.
I'm Michaela. I've kept tanks for over a decade — bettas, Crystal Reds, planted scapes. Built Blissfish after losing two acros to alkalinity drift I should have caught a week earlier. If you've ever stood in front of your tank with a test strip in one hand and a spreadsheet in the other, this is for you.

The questions serious aquarists actually ask.
Test strips are inherently variable — that's true for every strip on the market. We built Strip Scanner for quick daily checks, not precision measurement. For breeding, reef work, or anything where precision matters, use the Liquid Test Reader with API, Salifert, Red Sea, or Tropic Marin kits.
Neptune Apex and Focustronic integrations are available at launch. Profilux, Home Assistant, Trident, and others are on the roadmap. If your controller has an API and you want it integrated, tell us — popular requests move up the list.
They're tracking tools. Blissfish is a tracking tool that also schedules maintenance, journals your tank, predicts breeding outcomes, integrates with your gear, and grows with your hobby. Try the free tier and see for yourself. Then export your data if you want to leave — we don't lock anyone in.
No, and we wouldn't call it that. It's rule-based Punnett-square logic for known Caridina recessive traits. The same genetics serious shrimp keepers already use — just automated, with lineage tracking and grading built in.
Export to CSV anytime, with one tap. Your data belongs to you — not us. We don't sell tank data, and we never will. If we ever shut down, we'll give you at least 90 days' notice and a final full export.
It's real. The founding price is $99 one-time. We may raise it as the product matures — that's the founding part. But anyone who claims it locks in lifetime access at $99 forever, no future fees, no clawbacks.
Yes. Custom parameters per tank means whatever you measure, you can log. Planted, reef, brackish, breeding setups — all in the same app, with no awkward freshwater/saltwater toggle.
Yes. Blissfish Studio is built for this — multi-user access (up to 5 seats), inventory mode with stock counts and pricing, bulk operations across tanks, custom branding, and priority support. $29/month or $290/year. Get in touch if you need more than 5 seats.
Lineage tracking works for any species — shrimp, fish, anything. Cross Predictor is live for Caridina and Neocaridina shrimp, in beta for bettas, guppies, and clownfish designer morphs. For discus, killifish, and cichlids, we offer lineage and pedigree tracking but no prediction — those genetics aren't tractable enough to predict honestly. We'd rather give you good tools than fake answers.
