Splash Tetra

🔥 Splash Tetra (Copella arnoldi)

Add something truly unique and fascinating to your aquarium with the incredible Splash Tetra. Famous for its unusual breeding behaviour, this species is known for leaping out of the water to lay eggs on overhanging leaves above the surface. Combined with its sleek silver body and subtle red and yellow accents, it’s a real conversation starter in any setup.

Splash Tetras are peaceful, active, and ideal for aquarists looking for something a little different from standard schooling fish.

🌿 Why Choose Splash Tetra?

💦 Unique “splashing” surface-spawning behaviour
🐠 Peaceful and active schooling fish
✨ Sleek silver body with subtle red/yellow highlights
🌱 Great for planted aquariums with surface cover
⭐ Unusual and highly interesting species in the UK

When kept in groups, Splash Tetras form a lively shoal that spends much of its time in the mid to upper water levels, creating constant movement and interest.

Splash Tetras prefer well-planted aquariums with plenty of surface plants or overhanging leaves. A tight-fitting lid is essential due to their natural jumping behaviour.

🐠 Compatibility

Best suited to peaceful community aquariums with other small, calm species such as tetras, rasboras, Corydoras, and small gouramis. Avoid aggressive or large fish that may stress them.

Important Notes

Splash Tetras are surface spawners and may jump during breeding behaviour, so a secure lid is absolutely essential. They are best kept in mature, well-planted aquariums where they feel secure and display natural behaviour.

The Splash Tetra is a fantastic choice for UK aquarists looking for a rare, interesting, and behaviourally unique fish that adds life, movement, and something truly different to planted and community aquariums.
