Start with a mature, filtered aquarium at least 60 cm long. Published size records disagree, and broad group guidance is not Honey-Gourami-specific, so verify Trichogaster chuna, the seller's adult-size advice and any claimed sexes before choosing one fish or a group.
Maintain these water conditions for optimal health and vibrant colors
The orange thick-lipped gourami is an aquarium-bred colour form of Trichogaster labiosa (formerly Colisa labiosa), a peaceful labyrinth fish from Myanmar that breathes air at the surface. Its body is golden to orange in place of the natural olive-brown colour, and the colour deepens as the fish settles and matures. FishBase gives a maximum length of about 9 cm.
This listing is the orange form. The natural-coloured thick-lipped gourami is sold as a separate listing.

Choose 2.5–3 cm, 3–4 cm or 4–5 cm, then the quantity. One quantity is one live orange thick-lipped gourami, unsexed. Young fish are paler and colour up as they grow.
A calm, mature planted aquarium of about 80 litres or more suits this species, with floating plants to soften the light, gentle flow and a tight lid that keeps the air above the water warm — gouramis breathe air at the surface. Keep 22–27°C, pH 6.0–7.5 and 5–15 dGH, the range in Seriously Fish, with regular partial water changes.
An omnivore: feed a quality flake or small pellet daily, with small frozen or live foods such as bloodworm, Daphnia and brine shrimp a few times a week.
Peaceful and somewhat shy. Good with calm fish of similar size such as rasboras, peaceful barbs, Corydoras and other gentle gouramis; males can be territorial with each other, so keep one male per smaller aquarium. Avoid fin-nippers and boisterous tank mates.

What customers say about ordering from us
I have a small group of long finned mountain minnows. So was delighted to be able to order ten of this variety to increase the genetics in my tank . The ones I recieved are healthy but it’s to early to give a verdict on wether they are of a long finned type since they are small currently.

100% success travel and "installation". Pleased with quality of purchase. The Siamese fighter a bit "shy" so have not yet seen him at his best yet but looking good. Happy customer. GG
