Tomato Clownfish

The Tomato Clownfish, Amphiprion frenatus, is one of the most eye-catching clownfish varieties available for marine aquariums. Its deep orange to tomato-red body, contrasting darker tones as it matures, and active swimming pattern make it a standout display fish for saltwater hobbyists. This species is often chosen by aquarists who want a hardy clownfish with bold colour and a stronger personality than many smaller reef fish.

Tomato Clownfish usually adapts well to established marine aquariums with stable salinity and good filtration. Juveniles often show brighter orange shades, while adults develop a richer red tone and a more robust body shape. Like many clownfish, it can become territorial around its chosen shelter, host coral, or anemone, so tank planning and compatible stocking are important for long-term success.

Key Features

• Appearance: Bright red-orange to tomato-red marine fish with a compact clownfish body shape and a bold, highly visible display presence.
• Size: Commonly sold as a manageable aquarium specimen, with adults capable of reaching around 12 to 14 cm in home aquariums.
• Colors: Vivid orange-red body with darker maturity tones and a characteristic white head bar, giving it a classic but more intense clownfish look.
• Lifespan: With stable marine conditions, proper feeding, and low stress, this species can live for several years in captivity.
• Temperament: Semi-aggressive and territorial, especially as it matures or claims a cave, rock crevice, coral area, or host spot in the tank.
• Water Type: Marine species that requires clean saltwater, stable salinity, and a mature biological system.

Care Requirements

• Tank Size: A tank of at least 30 gallons is recommended for a single Tomato Clownfish, with larger tanks preferred for mixed marine communities or pairs.
• Water Parameters: Best kept at 24 to 27°C, pH 8.1 to 8.4, and stable marine salinity around 1.020 to 1.025 specific gravity.
• Diet: Omnivorous; feed a varied marine diet including quality marine pellets, frozen meaty foods, mysis shrimp, brine shrimp, and occasional algae-based foods.
• Tank Mates: Suitable with other marine fish that are not overly timid or aggressive. Avoid mixing with multiple clownfish species in smaller tanks to reduce territorial conflict.
• Care Tips: Provide rockwork, caves, and defined shelter zones. Introduce into a mature tank, maintain strong filtration, and avoid sudden swings in salinity or temperature.
• Reef Suitability: Often kept in reef-style systems, but compatibility should always be judged based on tank size, coral placement, and overall stocking behaviour.

For best results, add Tomato Clownfish to a stable marine aquarium that has completed cycling and has dependable filtration and regular maintenance. Its bold colour and confident nature make it an excellent centrepiece fish for hobbyists building a lively saltwater display.
