Blue Gularis Killifish

The Blue Gularis Killifish is one of the most spectacular killifish available to freshwater aquarists, admired for its intense blue and red colouration, shimmering scales, and flowing fins. Males can display brilliant electric-blue bodies covered with red spots and markings, creating an incredibly eye-catching fish that stands out beautifully against a dark, planted aquarium.

Despite their impressive appearance, Blue Gularis Killifish are relatively peaceful when kept with suitable tankmates. They are active and inquisitive fish that spend much of their time exploring the aquarium, particularly around dense vegetation and shaded areas.

🌿 Why Choose Blue Gularis Killifish?

• 💙 Stunning metallic blue body colouration
• ❤️ Striking red spots and markings
• ✨ Males develop spectacular flowing fins
• 🐟 Fascinating and active behaviour
• 🌱 Excellent choice for planted aquariums
• 🎨 Males and females have distinctive differences in colour
• 🏆 A spectacular centrepiece fish for experienced aquarists

Blue Gularis Killifish are native to parts of West and Central Africa, particularly areas of Cameroon and neighbouring regions. They inhabit slow-moving waters, streams and seasonal habitats where dense vegetation provides shelter.

Their natural environment often contains soft, slightly acidic water with plenty of vegetation, shaded areas and subdued lighting. Replicating some of these conditions in the aquarium can help Blue Gularis feel secure and display their best colours.

📏 Care Requirements

🧬 Scientific Name: Fundulopanchax sjoestedti
📛 Common Name: Blue Gularis / Gularis Killifish
🏠 Tank Size: 60L+ recommended
📏 Adult Size: Up to approximately 10–12cm
🌡️ Temperature: 22–26°C
⚗️ pH Range: 6.0–7.5
🧘 Temperament: Generally peaceful, but can be territorial
🍽️ Diet: High-quality pellets and flakes, frozen foods, bloodworm, daphnia, brine shrimp and other small live foods
👥 Group Size: 1 male with 2–3 females recommended

Blue Gularis appreciate a mature, well-planted aquarium with plenty of cover. Floating plants are particularly useful for providing shade and helping these fish feel secure.

A dark substrate and subdued lighting can help bring out their spectacular colours, while open areas should still be provided for swimming. A tightly fitting aquarium lid is essential, as Killifish are excellent jumpers and can escape through surprisingly small gaps.

🍽️ Feeding

Blue Gularis Killifish are naturally carnivorous and particularly enjoy meaty foods. A varied diet helps maintain their condition and encourages strong natural colouration.

Suitable foods include:

• 🦐 Brine shrimp
• 🪱 Bloodworm
• 🦠 Daphnia
• 🦐 Mysis shrimp
• 🍽️ Quality carnivorous micro pellets
• 🐟 High-quality flakes
• ✨ Other suitable small frozen or live foods

Offering a mixture of quality prepared foods and frozen or live foods is ideal.

🐠 Compatibility

Blue Gularis Killifish can be kept in a peaceful community aquarium with appropriately sized, non-aggressive species. Suitable companions may include:

• 🐟 Small to medium-sized Tetras
• 🐟 Rasboras
• 🐟 Corydoras
• 🐟 Small peaceful Loricariids
• 🐟 Other similarly sized peaceful community fish
• 🐌 Larger peaceful freshwater snails

Avoid very small fish and shrimp, as larger Blue Gularis may view tiny tankmates as potential prey. They should also not be housed with aggressive species or persistent fin-nippers.

Males can sometimes be territorial towards one another, particularly in smaller aquariums, so keeping a single male with several females is often preferable.

Important Notes

Blue Gularis Killifish are best suited to aquarists who can provide a mature, stable aquarium with plenty of cover. Although they can be peaceful, males may become territorial, particularly when kept together without sufficient space or hiding places.

Males are considerably more colourful than females, developing the characteristic blue body, red markings and elongated fins. Females are generally smaller and much less vividly coloured.

They can be bred in the aquarium, with eggs deposited among suitable spawning material such as fine-leaved plants or spawning mops. Breeding conditions and egg development can vary depending on the setup and temperature.

Their jumping ability should not be underestimated. Always keep the aquarium securely covered, particularly around filter openings, cables and other gaps.

Blue Gularis Killifish are a fantastic choice for aquarists looking for something different from the usual community fish. Their spectacular metallic blue colouration, vivid red markings and flowing fins make them a stunning feature in a well-planted aquarium, while their fascinating behaviour makes them particularly rewarding to keep.
