Discus
Symphysodon aequifasciatus

Accessories
API Freshwater Master Test Kit
Absolutely essential for Discus keepers. These beautiful fish require warm (28-32°C), soft, slightly acidic, chemically pristine water. Any fluctuation in ammonia, nitrite, or nitrate can cause stress and disease within hours. 800+ tests covering all critical parameters.
Seachem Prime Water Conditioner
Prime is non-negotiable for Discus tanks. These fish are kept at high temperatures where bacteria multiply quickly — Prime detoxifies ammonia and nitrite between water changes, buying time in the frequent, large water changes that Discus require.
Food
Sera Discus Color Nature
A premium discus-specific diet with natural astaxanthin and spirulina that intensifies the breathtaking colors of Discus without artificial dyes. Soft granules are easy to digest, and the high-quality protein blend supports active warm-water fish. Feed multiple small portions daily.
Hikari Vibra Bites
Slow-sinking sticks that mimic live bloodworms — the favorite treat of Discus. Offering Vibra Bites several times a week supplements their staple diet with high-quality protein and encourages the natural predatory feeding behavior Discus perform in the wild.
Heating
Eheim Jager 75W Heater
Discus require stable temperatures of 28-32°C that most heaters cannot maintain accurately. The Eheim Jager is one of the most precise and reliable heaters available, with a recalibration system that keeps temperature variation to ±0.5°C — essential for these demanding fish.
