German blue rams are among the most beautiful fish in the hobby — small, peaceful dwarf cichlids in electric blue and gold that suit a community tank. They are not quite beginner fish, though: they need warm, clean, stable water and are sensitive to poor conditions. Get that right and they reward you with colour and personality. This UK guide covers German blue ram care.

Here’s how to keep them.

Quick facts

• Adult size: 5–7 cm
• Tank size: 75 litres for a pair
• Water: pH 5.5–7.0, soft, 27–30 °C (warm!)
• Lifespan: 2–4 years
• Temperament: peaceful dwarf cichlid

They need warmth and clean water

Rams come from warm waters and need 27–30 °C — warmer than most community fish, which limits tank mates. They are also sensitive to ammonia and nitrite, so they must go in a mature, fully cycled tank with pristine water. Many ram deaths come from adding them to a new tank. Use a reliable heater and a good test kit.

Tank setup and feeding

Provide a soft-water, planted tank with caves and gentle flow. Feed a varied diet of quality micro granules and frozen foods like bloodworm and brine shrimp to bring out their colour.

Tank mates

Choose heat-tolerant, peaceful fish: rummy nose and cardinal tetras, rasboras, sterbai corydoras and otocinclus. Avoid aggressive fish and anything that can’t handle the high temperature.

Frequently asked questions

Are German blue rams hard to keep?

They are moderately demanding — peaceful and beautiful, but sensitive to poor water quality and needing warm water of 27–30 °C. They must go in a mature, fully cycled tank with pristine conditions.

What temperature do German blue rams need?

27–30 °C, warmer than most community fish. This high requirement limits which tank mates can comfortably live with them.

Why do my German blue rams keep dying?

Most often because they were added to an immature tank or one with ammonia or nitrite present. They need a fully cycled, stable, warm, soft-water tank with excellent water quality.
