Will honey gouramis nip at cardinal tetras?

No. Honey gouramis are calm, peaceful fish that rarely nip at other tankmates. They may flare at each other occasionally but leave cardinal tetras alone.

How many honey gouramis can I keep with cardinal tetras?

One male honey gourami does well with a school of six or more cardinal tetras in 15-20 gallons. A pair of one male and one female also works. Keep only one male to avoid gourami-to-gourami aggression.

Do honey gouramis carry the same disease risk as dwarf gouramis?

No. Honey gouramis are generally hardier and have a much lower rate of iridovirus than dwarf gouramis. They are a better choice for a community tank if disease concerns are a priority.

Can Cardinal Tetra Live With Honey Gourami?

By Alex WalshLast reviewed Apr 18, 2026

It depends

Maybe, with caveats , cardinal tetras and honey gouramis share a wide temperature range and occupy different tank levels, which suggests peaceful coexistence, but both species prefer soft, slightly acidic water that must stay stable.

Why

Temperature overlap of 73-81°F covers both species comfortably, with honey gouramis preferring the warmer end around 76-80°F.
pH overlap of 6.0-7.0 works well for both species, leaning toward slightly acidic water that brings out cardinal tetra colors.
Honey gouramis are labyrinth fish that breathe air at the surface while cardinal tetras school mid-tank, so they occupy different zones.
Honey gouramis are among the more peaceful gourami species and rarely bother tankmates.
Both species do best in planted tanks with gentle filtration and stable water conditions.

Minimum shared tank

What could go wrong

Both species are sensitive to water quality swings, and a spike in ammonia or nitrite will hit them harder than hardier fish.

Better pairings to consider

Honey gouramis do well with corydoras, otocinclus, or peaceful rasboras. Cardinal tetras do well with ember tetras, rummy-nose tetras, or other soft-water community fish.
