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
Short fins, big attitude. Plakats are the traditional short-finned form of Betta splendens, and this fancy colour mix delivers males of around 6.5 cm in whichever multi-coloured fancy pattern the draw produces — every fish a one-off, every fish carrying the compact, athletic build that sets plakats apart from their long-finned cousins. Keepers often choose plakats precisely for that agility: without trailing finnage to haul around, they are quick, alert and constantly on patrol.
That energy comes with a warning label. This line is recorded as genuinely aggressive, so treat him as a solo fish first and foremost. Snails are the safest companions; peaceful shrimp may be workable in a larger, well-planted tank, though some individuals will prey on them. Do not attempt other male bettas, fin-nipping species such as tiger barbs, territorial fish, long-finned tank mates that trigger flaring, or fast boisterous species that keep him permanently on edge. He claims the top of the water column and will defend it. The record asks for a 40-litre minimum — generous for a betta, and exactly what an active plakat will actually use — with water at 24–30 °C, pH 6.0–7.5 and hardness between 1 and 15 dGH.
Plakat keeping has its own rhythm. Because he carries no heavy finnage, this male swims constantly and burns through energy faster than show-finned types, so split his carnivore ration into smaller, more frequent feeds where you can. He will use every centimetre of the recorded 40 litres, particularly the length of the tank rather than its depth — floor space beats height for an active surface fish. Enrichment genuinely matters with fancy plakats: rearrange a plant occasionally, vary where food lands, and his alertness stays sharp across the three years his record projects. Water duties are unremarkable — hold 24–30 °C, keep pH inside 6.0–7.5, and test hardness stays within the 1–15 dGH band.
Fancy-mix fish are supplied by pattern category, not by photograph, so the exact colours of your male will be unique to him. He may turn more territorial as breeding condition develops. Delivery across the UK uses a licensed live-animal courier and carries our live arrival guarantee.
