The honest cost

How much does a Croaking Gourami cost to keep? — the croaking gourami itself is usually the cheapest part.

The honest answer: the croaking gourami itself is usually the cheapest part. Here's what it really costs — the upfront setup, the ongoing monthly costs, and where it's safe to save vs never cut corners. We don't quote prices (they vary by country, currency and month) — we show you what you're paying for and where the money actually goes.

💷 Upfront — the one-time setup

What you need before the croaking gourami comes home. The setup, not the fish, is the real cost of entry.

The tank: Sized for an adult (A single pair does well in a 60 x 30 x 30 cm tank, about 54 litres (14 US gallons) - that is the SeriouslyFish footprint and the honest floor. Pet-shop labels often quote 40 L / ~10 gal; that scrapes by for one fish, but the 60 cm footprint gives far better surface space, cover and water stability. For a small group go wider and longer, not just taller: floor area and surface area matter more than raw volume for a slow, surface-breathing fish. Never a bowl, vase or unheated nano cube.). This is the single biggest cost — and the number-one thing beginners under-buy. A bigger tank is more stable AND cheaper than replacing a small one you've outgrown.
A filter: A filter rated comfortably above the tank volume (Gentle. This is a slow, surface-oriented fish from still and sluggish waters, so use a filter with mild output (sponge filter or a baffled/low-flow filter). Keep the surface calm but not stagnant; strong current stresses it and stops males building a bubble nest. Cycle the filter fully before adding fish.). Under-filtering causes most of the problems people blame on the fish — the bigger, right filter is the cheap insurance.
Substrate, décor & plants: The substrate, hides, and real or silk plants. This is where you CAN save — sand/plain gravel, DIY hardscape and hardy plants do the job as well as branded aquascaping kit.
A water test kit + dechlorinator: A liquid test kit (ammonia, nitrite, nitrate, pH) and a water conditioner. These are essential, not optional — you cannot keep fish safely without testing your water and dechlorinating every top-up and water change.
The fish itself: Usually the SMALLEST line on this whole list. The price of the croaking gourami tells you almost nothing about the cost of keeping it well.

🔁 Ongoing — the part people forget

The costs that keep coming for the fish's whole life (Typically about 3-5 years with good, stable water; 4-5 years is a realistic average in a well-kept planted tank.).

Food: Its diet (Micro-predator / omnivore leaning carnivore. Takes good-quality micro-pellets and flake, but relishes small live and frozen foods: daphnia, brine shrimp (Artemia), bloodworm and other chironomid larvae, and micro-worms. A varied diet with regular live/frozen foods brings out colour and breeding condition.). Modest per month, but constant for the fish's whole life — and this species can live Typically about 3-5 years with good, stable water; 4-5 years is a realistic average in a well-kept planted tank..
Electricity: The hidden monthly cost: the filter run 24/7. Over a year the power bill can quietly rival the food bill — and it scales with a bigger, correct tank.
Consumables: The recurring replacements: dechlorinator / water conditioner, test-kit refills, replacement filter media, and — if you keep live plants — root tabs or liquid ferts. Small, regular, easy to forget when you budget.
Vet care: Aquatic / fish vets are rare and pricier than a cat-or-dog vet, so keep an emergency mindset and a small fund. Reptiles and fish alike hide illness until it's advanced. Find a fish vet BEFORE you need one — start with the Croaking Gourami vet-prep sheet below.

✅ Worth the money

Water first: target soft, slightly acidic to neutral water - about pH 6.0-7.5 and 1-12 dGH - held at a stable tropical 24-27 C (75-81 F). It tolerates a wider band (down to pH ~5 and up to moderately hard), but soft and acidic is where it thrives and breeds.
Cycle the tank before any fish go in. Run the nitrogen cycle to completion so ammonia and nitrite read 0 ppm and nitrate stays low with weekly water changes. A small nano volume swings fast, so test and change water regularly rather than trusting a heater-and-hope bowl.
Footprint over height: the SeriouslyFish reference is a 60 x 30 x 30 cm tank (~54 L / 14 US gal) for a pair. Choose length and surface area over a tall nano cube - surface access is life-or-death for an air-breather. The common 40 L / 10 gal 'minimum' is a floor for one fish, not a target.
A secure, tight-fitting LID is non-negotiable. Labyrinth fish gulp air at the surface and are described as excellent jumpers; an open or gappy tank invites a carpet death. Leave a gap of humid air between the water and the lid - do not fill to the brim - because both adults and (especially) fry need that warm, humid air layer to develop the labyrinth organ properly.
Aquascape for a shy fish: heavy planting, floating plants to shade and dim the surface, plus wood, leaf litter and caves for broken sightlines and hiding spots. A darker substrate deepens its colour. Keep flow gentle and the surface calm so bubble nests can hold.
Keep the room and tank calm and warm. Sudden chills, a cold draught over the surface, or being placed by a busy walkway keeps this timid fish hidden and silent. A stable, warm, quiet tank is what unlocks its personality and its croak.

🟡 Save your money

All-in-one "starter kit" bundles that lock you into a small tank — the tank is usually the wrong size, so the "saving" costs you an upgrade.
Decorative gimmicks — coloured gravel, plastic ornaments and novelty décor do nothing for the fish; plain substrate, wood, rock and plants are cheaper and better.
Gimmick "cures", tonics and clarifiers — most mask a water problem instead of fixing it. A test kit and water changes are the real fix.

⛔ Never buy

A fish BOWL or vase — no room, no filter, no heater. It is the number-one cause of avoidable fish death, not a starter home.
A tank sold as a "complete setup" that is too small for a croaking gourami — you will pay twice when you have to upgrade.
No dechlorinator — tap water contains chlorine/chloramine that kills fish and the beneficial bacteria your filter needs. This is never the place to save.
An undersized filter to "match" a small tank — under-filtering is behind most water-quality problems.

Cheap, common, and harmful — true for every freshwater fish.

The one rule on cost: budget where it's safe — a second-hand tank, DIY or plain décor and substrate — but never cheap out on the tank size, the filter, a dechlorinator, or a test kit. Those are where cutting corners costs the croaking gourami its health, and usually costs you more later. We don't quote prices — check current local prices where you live; this is what to budget for.

Cost questions

How much does a croaking gourami cost to keep?

More than it costs to buy — the croaking gourami is usually the cheapest part. The real cost is the setup (the tank, a filter, substrate and décor, and a test kit plus dechlorinator), then the ongoing food, electricity, consumables and vet care. We don't quote a figure because prices vary a lot by country, currency and month — this page shows exactly what you're paying for and where the money goes, so you can price it up locally.

What are the ongoing monthly costs of a croaking gourami?

Food, electricity for the filter that run 24/7, recurring consumables (dechlorinator, test-kit refills, filter media), and — the big variable — vet care: keep a small emergency fund, because fish vets are rare and pricier. This species can live Typically about 3-5 years with good, stable water; 4-5 years is a realistic average in a well-kept planted tank., so these small monthly costs add up over its life.

Why does the setup cost more than the croaking gourami itself?

Because you're not buying a fish — you're building its whole environment. A croaking gourami needs its tank, a cycled filter, and clean, tested, dechlorinated water, and that equipment is where the money goes. The purchase price of the croaking gourami tells you almost nothing about the cost of keeping it properly.

Where can I save money on a croaking gourami — and where shouldn't I?

Safe to save: budget on décor and substrate, and buy a second-hand tank (glass lasts). Never cheap out on the tank SIZE, the filter, a dechlorinator, or a test kit — those four are where saving money costs the fish its health, and usually costs you more later.
