Small labyrinth fish, not a betta clone
Trichogaster chuna (still sold as Colisa chuna) is a Southeast Asian labyrinth fish that gulps air at the surface. Adults top out around 1.5–2 inches. Males color up gold to amber on the body and throat; females stay plainer. They are slower and less territorial than a male betta, which is why they work as a planted-community centerpiece instead of a solo fighter.
Keep the surface accessible. Floating plants are fine if they leave open pockets. They still need a heater and a filter. A vase or unheated bowl is not a home. Gentle flow (sponge filter or a baffled hang-on-back) matches their quiet swimming style.
Ten gallons alone, twenty for a pair
One honey gourami is comfortable in a planted 10-gallon with a heater, lid, and soft cover. A pair or a real community wants a 20-gallon so each fish has room to ignore the other. Length and plants beat a tall hex. See stocking a 20-gallon tank for layouts that leave midwater space for rasboras and tetras.
Temps in the 72–82°F band work for most shop fish. Soft to near-neutral water is preferred; hard alkaline livebearer tanks are a long-term mismatch. Finish the cycle before you buy. Quarantine new fish when you can. Shop stock mixes, and gouramis are not immune to hitchhikers.
Honey vs dwarf gourami
Dwarf gourami (Trichogaster lalius) is a different species. Farmed dwarfs are often sold as 'honey,' 'sunset,' or 'powder blue' color morphs. True honey gouramis stay smaller and calmer; dwarfs run larger, flashier, and more aggressive male-to-male. If the bag fish is powder blue or neon orange with a high, pointed look, you probably bought a dwarf.
Dwarf gourami iridovirus (DGIV) is common in mass-farmed dwarfs and has no cure. That is why honey is the easier pick for a peaceful labyrinth fish. If you still want a dwarf, the dwarf gourami page covers how to buy a healthy one. Buy by scientific name when the label is vague, and quarantine anyway.
Food and tank mates
Feed micro pellets or flake they finish in a minute, then add frozen a few times a week. Leftover food in a planted 10 is how nitrate climbs. Tank mates that work: harlequin rasboras, cherry barbs in a planted 20, neons or cardinals if parameters overlap, a cory group on sand, and adult cherry shrimp. Skip male bettas, tiger barbs, and packing two male gouramis into a 10.
They are timid compared with danios. Dimmer light, stem plants, and a bit of hardscape help them show color. A male will sometimes build a bubble nest. That is normal breeding behavior, not a reason to panic-medicate.
