Care guide
Everything you need to keep Blue Tang healthy in a South African setup.
Water parameters
Keep pH 8–8.4 and 24–27°C. Stable parameters matter more than chasing perfect numbers — acclimate new arrivals slowly.
Feeding
Blue Tang is an omnivore. Feed a varied diet appropriate for saltwater fish — quality flakes, pellets, or frozen foods sized to the mouth.
Behaviour
Blue Tang is generally peaceful. Observe during feeding and at lights-out for true temperament.
Tankmates
Pair with similarly sized peaceful tankmates in saltwater fish. Avoid fin-nippers or species that outgrow this fish.
Breeding
Breeding notes for Blue Tang vary by line and water chemistry — ask your local shop about proven pairs in SA.
Keeping marine fish?
