Frequently Asked Questions about Discus

How hard are Discus to keep?

Discus are intermediate-to-advanced fish. They need pristine water (nitrate under 10ppm), warm temperatures (28–30°C), soft acidic water (pH 6.0–7.0 ideally) and frequent large water changes. Healthy captive-bred UK Discus from a trusted source are much more forgiving than wild-caught specimens.

What size tank do Discus need?

A minimum of 200L for a shoal of 6 adults — Discus are shoaling cichlids and stress in smaller groups. Height matters: at least 45cm tall to accommodate their body shape. Larger tanks (300L+) dilute waste better and give more stable water chemistry.

What can I keep with Discus?

Tankmates must tolerate warm, soft water. Cardinal Tetras, Rummy Nose Tetras, Sterbai Corydoras and L046 Zebra Plecos are traditional Discus companions. Avoid fast or fin-nippy fish that outcompete Discus at feeding time.

How often do I need to do water changes on a Discus tank?

Traditional Discus keeping relies on 50% weekly water changes, sometimes more for growing fry. Stable keepers may get away with 30% weekly once the tank is mature and lightly stocked. Always dechlorinate and temperature-match incoming water.

Do Discus need a planted tank?

No, but plants help. Amazon Swords, Anubias and Vallisneria tolerate the warm water Discus prefer and give cover that reduces stress. Bare-bottom breeding tanks are common too, trading aesthetics for easier cleaning and better growth rates.
