Shoaling fish: kept in a group they feel safer, stay calmer and show their best colour.

Kuhli loaches are peaceful, slender Pangio loaches that need an established, escape-resistant aquarium with cover and a social group. As a conservative UK planning floor, use at least five compatible individuals and an aquarium of at least 80 litres for the smallest loaches; adult identity, dimensions, water, companions and filtration can require more.
Maintain these water conditions for optimal health and vibrant colors
Brown Kuhli Loach is a peaceful, eel-like Pangio loach for soft planted aquariums with sand, leaf litter and shaded hiding places. The supplier trade label for this SKU is Pangio kuhlii javanicus; brown kuhli-type loaches can be traded under several closely related names.

Keep Brown Kuhli Loaches in a settled aquarium with fine sand, smooth wood, leaf litter and plenty of cover. They are social fish, so a group of five or more is far better than a single specimen. They spend much of the day hidden and become more active in the evening, especially when the tank is calm.
Use gentle but reliable filtration and keep ammonia and nitrite at zero. Sharp gravel is a poor choice because these loaches probe and burrow around the substrate with delicate barbels. A tight lid is sensible, as slim loaches can squeeze through small gaps.
Offer sinking foods after the lights dim so the loaches are not outcompeted by midwater fish. Small pellets, soft wafers, frozen bloodworm, daphnia and cyclops all work well. They will browse leftover particles, but they should never be expected to live on scraps alone.
Choose peaceful fish that enjoy similar warm freshwater conditions. Calm companions such as Neon Green Rasbora and Green Neon Tetra work well above the loaches, while other loaches such as Zebra Loach or specialist hillstream species such as Panda Loach should be compared carefully because their flow and space needs can differ. Avoid large cichlids, rough bottom dwellers and fin nippers.

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
