Fire bar danio tank size
Seriously Fish recommends a minimum tank length of 75 cm and a tank width of 30 cm. Seriously Fish gives an adult length of 5 cm standard length for this species.Seriously Fish recommends a minimum tank length of 30 in and a tank width of 12 in.

This species originates from the Mae Nam Ping drainage in the upper Chao Phraya basin of northern Thailand. Their natural habitat consists of clear small streams with sand, gravel and rock substrates without aquatic vegetation. You can replicate this environment with a stream-style layout.This species originates from the Mae Nam Ping drainage in the upper Chao Phraya basin of northern Thailand.

Design the display using water-worn rocks, sand, fine gravel, boulders and roots. You can attach plants such as Microsorum, Bolbitis or Anubias to hardscape features. Always fit a tightly fitting lid, as this group is known for jumping.Design the display using water-worn rocks, sand, fine gravel, boulders and roots.

This fish is also sold as the fire bar or tiger danio, and was formerly known as Devario maetaengensis, though its classification is currently 'Inlecypris' maetaengensis. It is easily confused with Inlecypris shanensis and Devario interruptus. Proper identification relies on barbels, lateral-line structure and flank patterns.This fish is also sold as the fire bar or tiger danio, and was formerly known as Devario maetaengensis, though its classification is currently 'Inlecypris' maetaengensis.

Fire bar danio water parameters
Maintain water temperature between 22–26 °C, with a pH of 6.0–8.0 and water hardness between 3–10 dGH. These values represent the overlapping ranges between general aquarium guidance and species records.Maintain water temperature between 72–79 °F, with a pH of 6.0–8.0 and water hardness between 3–10 dGH.

Provide clean water with moderate movement and relatively high dissolved oxygen. Very fast flow is unnecessary.Provide clean water with moderate movement and relatively high dissolved oxygen. Very fast flow is unnecessary.[1]
Establish biological filtration thoroughly before introducing any fish to the aquarium. Ammonia should be undetectable and nitrite controlled. Clear-looking water alone cannot prove chemical safety, so test ammonia weekly and whenever appetite or behaviour changes.Establish biological filtration thoroughly before introducing any fish to the aquarium.

Feeding fire bar danios
Follow general RSPCA feeding guidance by offering two small meals daily, each limited to what the fish actually consume in about two minutes. Adjust portion size to the fish and remove uneaten food after feeding.Follow general RSPCA feeding guidance by offering two small meals daily, each limited to what the fish actually consume in about two minutes.

Fire bar danio behaviour
The fire bar danio is a peaceful schooling fish suitable for a well-chosen community setup. Keeping them in a group of eight or more helps reduce nervousness, and competing males display richer colours in the presence of rivals.The fire bar danio is a peaceful schooling fish suitable for a well-chosen community setup.

Breeding fire bar danios
This species is an egg-scattering free spawner without parental care. A separate dim breeding tank can use a base mesh, fine-leaved Taxiphyllum or wool mops. Include air-powered sponge filtration for oxygenation and movement.This species is an egg-scattering free spawner without parental care. A separate dim breeding tank can use a base mesh, fine-leaved Taxiphyllum or wool mops. Include air-powered sponge filtration for oxygenation and movement.[1]
Introduce one or two well-conditioned pairs to the breeding tank, and remove the adults after 48 hours. Incubation usually takes 24–36 hours depending on water temperature, with fry becoming free-swimming a few days later. Start feeding the young on Paramecium or similar foods, adding Artemia nauplii, microworms and powdered dry food once they are large enough.Introduce one or two well-conditioned pairs to the breeding tank, and remove the adults after 48 hours.

Fire bar danio health problems
Ich is a contagious protozoan infection affecting freshwater fish. Warning signs include white grains across the body or fins, rubbing against surfaces, excess mucus and reduced appetite. Reduce introduction risks by quarantining new stock for at least 30 days and using separate nets and siphons. Appearance alone cannot confirm the cause, so seek a prompt fish-health diagnosis.Ich is a contagious protozoan infection affecting freshwater fish.

Bacterial fin rot can cause progressive fin-edge erosion and redness or bloody streaks. Poor water conditions and stress favour bacterial infection. Prevent avoidable risk with clean water and protection from injury or harassment. Seek a proper diagnosis rather than assuming all damaged fins have fin rot.Bacterial fin rot can cause progressive fin-edge erosion and redness or bloody streaks.

Seek a proper diagnosis rather than assuming all damaged fins have fin rot.[4]
Ammonia poisoning damages delicate gill tissues, causes severe stress and can reduce feeding. Ammonia originates from fish metabolism as well as decaying food and waste. Prevent accumulation by cycling your biological filter thoroughly, avoiding excess feeding, and testing water regularly rather than diagnosing by appearance alone.Ammonia poisoning damages delicate gill tissues, causes severe stress and can reduce feeding.

What tank mates are compatible with danios?
Peaceful cyprinids, catfish and characins are suitable companion categories. Specific fish such as neon tetras, glowlight tetras, harlequin rasboras and zebra danios are conditional options once you verify shared water ranges and space for full groups.Peaceful cyprinids, catfish and characins are suitable companion categories.
