About this fish
Cardinal Tetra is a small, active schooling characin that shows its best colour and behaviour in a group. Peaceful and undemanding, it's ideal for planted community aquariums.
Care tips
- Keep in a shoal of at least 6 — lone specimens are shy and washed-out.
- Offer a varied diet of quality micro-pellets, flakes and frozen foods.
- Best in a planted tank with open swimming space and gentle flow.
