The betta fish is one of the most popular and most misunderstood freshwater species. This guide covers everything from proper tank size to the truth about tank mates.
Maintain these water conditions for optimal health and vibrant colors
Nemo is the betta hobby's name for a riot of orange, red and dark patches scattered koi-fashion across the body, and on the giant line that pattern gets a bigger canvas. This listing covers a young male Giant Nemo supplied at around the 4 cm stage, with the growing still to come — one of the pleasures of buying a giant early is watching the bulk and colour build together over the months after he settles in.
Moderate care suits this strain: nothing exotic in his requirements, but a keeper should be confident with heaters, cycling and water testing before taking him on. His temperament is recorded as aggressive, and the guidance leans hard toward keeping him alone or only with very carefully chosen, non-nippy company in a larger, well-structured aquarium. Peaceful snails are dependable; peaceful shrimp only stand a chance in heavy planting and only if this particular fish shows no predatory streak. Rule out other male bettas, fin-nippers, fast boisterous species like tiger barbs, long-finned fish that provoke him, and any shrimp or fish tiny enough to be hunted. Give him at least 30 litres at 24–30 °C, pH 6.0–7.5, and he will hold the top of the tank as his territory — more so if breeding condition sets in.
Raising a young giant is the part most keepers enjoy most. At 4 cm he has growing to do, and growth runs on feeding: small carnivore meals, twice daily if your schedule allows, build size steadily without fouling the water. His 30-litre minimum anticipates the adult he will become — buy the final tank now rather than upgrading mid-growth. Marble-gene fish like the Nemo line frequently shift pattern as they mature, so photograph him monthly; the record of changes becomes part of owning him. Keep temperature steady anywhere in the 24–30 °C band, hold pH between 6.0 and 7.5, and his moderate care rating asks nothing further beyond routine weekly water changes.
Every Nemo-patterned fish is a one-off print, so the male you receive will be patterned like no other — ours or anyone's. Order with confidence: insulated packing, a licensed live-animal courier, and our live arrival guarantee on every UK delivery.
