L177 Baryancistrus sp. - Catfish for Sale UK

Serious pleco keepers tend to ration tank space for fish like this one. L177 Baryancistrus sp. is a gold-marked South American catfish with a reputation as a rewarding but demanding charge — a strain for experienced aquarists who can run a warm, river-style aquarium and keep it stable. Heat is the headline requirement: this catfish wants water between 26 and 30°C, noticeably warmer than the standard community brief, with pH between 6.0 and 7.5 and soft to moderately hard conditions in the 2–12 dGH band.

Growing to around 12cm and living roughly ten years with consistent care, the L177 holds the bottom of the aquarium, working over surfaces as a primarily herbivorous aufwuchs grazer. Despite its Difficult care rating it remains a thoroughly peaceful fish, well suited to community life alongside small to medium tetras, rasboras, Corydoras, peaceful dwarf cichlids and other non-aggressive loricariids. What it cannot tolerate is competition for food: large aggressive cichlids, fin-nippers, highly territorial bottom dwellers and boisterous species that strip rations away before a methodical grazer can reach them all belong on the avoid list. A 150-litre aquarium is the minimum we recommend, giving the fish grazing territory of its own plus the water volume that makes high-temperature stability achievable.

Hardness deserves a moment’s attention too. The 2–12 dGH window leans soft, in keeping with the river-style brief, and the steadier you hold it the better this strain settles. Plan the bottom of the tank as its workplace: open grazing surfaces, broken sight lines, and enough floor space that Corydoras or fellow loricariids can pass through without friction. Meet those terms and the Difficult billing applies only to the spec sheet, not to the day-to-day.

Stocking notes before you buy

Prepare the aquarium before the fish: a mature 150-litre-plus tank already holding a steady 26–30°C is the difference between an L177 that thrives and one that merely survives. Choose calm midwater shoals over greedy feeders so its grazing patches go unplundered, and treat this as a decade-long commitment rather than a quick splash of gold for the substrate.
