BettaButler.
No more “oops,
sorry I forgot.”
An automatic feeder, an OLED clock and an optional water thermometer — all hidden inside one quiet disc that sits on your betta’s bowl. So you can travel, work late, and forget. Your fish won’t notice.

Depth: 6 m
Once every ten days.
A small, satisfying ritual.
~30 min · ONE TIME+~5 min · every 10 days
Step 01 · ~3 min
Clean your bowl.
Rinse the bowl with warm water — no soap, ever. A clean glass home is the foundation of a happy betta.
01
Fig. 01 · Empty bowl
Step 02 · ~5 min
Install the decoration.
Pour in your gravel of choice. Add driftwood, a small leaf hammock, anything your betta might call a landmark. Don't rush — this is the part where the bowl becomes a place.
02
Fig. 02 · Substrate
Step 03 · ~2 min
Pour the water.
Tap water is fine — bettas don't need bottled. Pour slowly to keep the gravel undisturbed. Fill until the rim is about a finger below the lip.
03
Fig. 03 · First pour
Step 04 · ~3 min
Add the water stabiliser.
A few drops of dechlorinator neutralise the chlorine and chloramine in tap water. Continue pouring while you swirl gently — the chemistry should mix as the bowl fills.
04
Fig. 04 · Conditioner
Step 05 · ~10–20 min
Let the chemistry settle.
Walk away. Make tea. The conditioner needs ten to twenty minutes to fully neutralise the chlorine and let the bowl come to room temperature.
05
Fig. 05 · Resting
Step 06 · ~1 min
Welcome home, betta.
Float the transport bag in the bowl for ten minutes to equalise temperature, then release. Your betta will hover, blink, and start exploring its landmarks.

Step 07 · ~2 min
Crown it with the disc.
Rest the BettaButler on the rim. One button. Set the hour you'd like the next feeding, choose the interval, done. The OLED counts down from this moment.
07
Fig. 07 · BettaButler · Aqua
Step 08 · ~2 min
Load ten meals.
Open the disc, fill each of the ten sealed compartments with a single portion of your usual food, snap the lid closed. You won't touch it again for ten days.

Step 09 · ten daysJust watch.
Just watch.
Isn’t it a small miracle?
You're done. For the next ten days, do nothing. Your betta is fed at the right hour, every day, in the right portion. The water stays clean. The bowl stays quiet. So do you.

An OLED that just tells you what you need.
No app. No account. No subscription. The 0.91″ OLED on the front of the disc shows the time, the next feeding countdown, and (on Plus) the current water temperature. That’s it. That’s the interface.

Three editions at retail: Solo €79 (feeder + USB-C), Plus €102 (adds live water temperature), Nomad Starter Kit €125 (Plus feeder + 10 L bowl + gravel — fish-ready in one box). Waitlist members get 20% off every edition with a personal code — that drops the prices to €63 / €82 / €100 respectively.
Free to join — just your email. The early-bird waitlist is capped at 100 spots; each member who joins before the cap receives a personal discount code by email when pre-orders open (end of July 2026). Apply the code at checkout for 20% off any of the three editions. The discount is yours to keep regardless of which edition you choose, or if you decide not to order at all.
Pre-orders open end of July 2026. Born in Ukraine · Made in Slovakia — first production batch begins August. Joining the waitlist gives you the exact pre-order opening date and time the moment it’s locked, plus early-bird pricing guaranteed.
The disc is a single 174 mm (Ø) part — it rests like a natural lid on round bowls with an opening of at least 156.5 mm (≈6.16 in). For bowls with a wider opening we offer base adapters that bridge the gap, so most pet-store sphere sizes still fit. Send us a photo if you’re unsure — we’ll measure together before you order.
Yes. EU buyers have a 14-day right of withdrawal from the day the product is delivered under EU Consumer Rights Directive 2011/83/EU — we’ll refund within 14 days of receiving the returned unit. US/UK/AU buyers get the same 14-day return window as a matter of policy.
Standard dry fish foods work: flakes, micro-pellets, granules, and freeze-dried foods. Each compartment holds a single, standard portion (about a pinch of flake or 4–6 micro-pellets) — you control the portion at fill time. One fill lasts up to 10 days at 1× daily, ~5 days at 2× daily, ~3 days at 3× daily. The OLED shows the next-feed time so you can pause feeding or load a compartment lightly if your fish reliably skips a meal.
Those are designed for rectangular tanks with a flat rim to clamp onto. BettaButler is a circular disc that sits on a round bowl like a natural lid — no clamps, suction cups, or mounting hardware needed. We also include live water temperature on the OLED display (Plus and Nomad), which competitor feeders in this price range don’t.
No. The waitlist is just your email — €0 today. You only pay when pre-orders actually open, and only if you decide to go ahead. The 20% discount code is yours regardless of whether you order.
