The Mangrove Jack (Lutjanus argentimaculatus) is a bold, fast-growing fish known for its strong personality and bright red-bronze colour.

If you want a standout fish, the Mangrove Jack For Sale is a great choice. It adds excitement and beauty to any large tank.

Size and Lifespan

Mangrove Jacks can grow very large. In the wild, they can reach up to 80 cm, but in tanks, they usually grow to about 50–60 cm. With good care, they can live for more than 15 years. To help them live longer, keep their water clean, give them lots of space to swim, and add things that keep them active.

Ideal Tank Setup

You should have at least a 1000-litre tank for one adult Mangrove Jack For Sale. Use soft sand or small gravel for the bottom. Add strong decorations like rocks, driftwood, and caves where they can hide. Keep the water temperature between 24–28°C, and the pH between 7.5–8.5. Also, make sure there is a good water flow. Don’t forget a strong lid—these fish can jump!

Compatible Tank Mates

Because they are aggressive and like to protect their space, the Mangrove Jack For Sale should be kept alone or with other big, tough fish. Good tank mates include large catfish or barramundi. Avoid keeping them with small or shy fish. These could be bullied or even eaten.

Feeding and Nutrition

Mangrove Jacks eat meat. They enjoy a mix of fresh or frozen seafood like prawns, fish pieces, and squid. You can also give them special pellets made for meat-eating fish. Feed them once or twice a day. Be careful not to give too much food, so the water stays clean.

Breeding and Behavior

Breeding Mangrove Jacks in tanks is hard because they need a lot of space and special conditions. In the wild, they move to the ocean to breed. They can be very smart and even learn to recognise their owners. Younger fish tend to hide more, while adults swim around boldly and show strong behaviour.
