Catalogued by collectors as L027, Panaque nigrolineatus is one of the celebrated wood-eating plecos — a heavyweight armoured catfish that turns a large aquarium into a proper showpiece. It is a fish bought with the long term in mind, because it grows substantial and lives for many years.
Adults reach somewhere in the region of 30–40 cm, so this is firmly a big-tank species. Remarkably for its size it is peaceful, content to graze the bottom and rasp at submerged wood, which forms a genuine part of its diet alongside other omnivorous fare. With good care it can live around 15 years.
The defining requirement is space and clean, well-oxygenated water: plan on at least 600 litres, with generous driftwood and strong filtration to cope with the waste a wood-grazer produces. It accepts soft to moderately hard water within the listed band, tolerating hardness from 0 to 15 dGH and warmth of 25 to 29°C, which is at the upper end and worth maintaining steadily.
People often ask what an L027 actually eats, and the answer shapes the whole setup: submerged wood is not optional decoration but part of its diet as a wood-grazing detritivore. Provide that, along with the room to grow towards 30 to 40 cm, and this is a peaceful giant that can share decades with you, with a potential lifespan of around fifteen years.
Care requirements
- Adult size roughly 30–40 cm; lifespan up to about 15 years
- Temperature 25–29°C, pH 6.0–7.5, hardness 0–15 dGH
- Minimum 600+ litres with plenty of driftwood; bottom-dwelling
- Omnivore and wood-grazing detritivore — driftwood essential
- Peaceful, moderate-care species for experienced keepers
Stocking note
Despite its bulk it mixes well with peaceful midwater fish such as tetras, rasboras and corydoras, other peaceful South American community fish, and non-aggressive cichlids of suitable size. Avoid aggressive or territorial fish, large predators, fin-nippers, very small fish that may be outcompeted for food, and other large wood-grazing plecos in undersized tanks. Its peaceful nature means it rarely causes trouble itself, so the main planning challenge is simply giving it the volume and driftwood a fish of this size demands. Each L027 Panaque ships with a licensed live-animal courier and our live arrival guarantee.

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
