Why pearl gouramis feel a move so keenly
A pearl gourami is a labyrinth fish: it rises to the surface to gulp air into a special organ, and that single fact shapes how it should travel. It is also a shy, deliberate fish that explores the world with the long, thread-like feelers on its underside, builds bubble nests among floating plants in breeding condition, and startles hard at sudden movement and noise. A gourami that spends moving day being chased, jolted and flashed with light often arrives refusing food and hiding for days. Prepare it instead for a slow catch, a roomy bag with a deep cushion of air, and a planted tank waiting at the other end.
Before moving day
Plan for the gourami to travel alone in its own bag or lidded container; tankmates bumping against it in the dark add stress it does not need, and a male gourami in particular does not want company in a confined space. Fill the container only partway with the gourami's own tank water and leave a generous air space above it, because the fish will keep rising to breathe during the journey and needs that air warm and humid. Stop feeding the day before so the travel water stays clean. At the new home, have the destination tank filled, filtered and planted before the fish arrives, with floating plants or tall stems breaking up the surface light.
Catching without a chase
Lower the water level in the home tank first so the gourami has less room to flee, then move slowly. The kindest tool is a clear container sunk in the water and guided around the fish with a gentle hand or soft net behind it; a gourami herded this way rarely panics. If you must net it, use a large, fine, soft net and support its body as you lift, taking care not to tangle or tear those long ventral feelers, which it uses like fingers and which are easily damaged. Work at the tank's usual light level rather than under a bright lamp, and keep voices and movement around the tank calm. Once the fish is in its travel container, cover it with a towel and leave it covered.
The journey and settling in
Carry the container upright in a dark box, away from direct sun and car-boot heat or cold, and resist opening it to check on the fish. On arrival, float the bag or container in the new tank to bring temperatures together, then open it and let the gourami swim out on its own into the plants with the lights low or off. Do not feed until the next day, and then offer a small amount of its usual food near the cover it has chosen. A settling gourami resumes its slow patrols and surface breaths within a day; one that stays clamped and hidden, refuses food for several days, or stops rising normally to breathe deserves a water check, and if nothing improves, a call to your vet. At the destination, a relative who has been given access to its profile through Family Sharing on KinsLe can open it while unpacking the fish.
