Overview
German blue rams add color on the sand. Angelfish need bigger tanks and eat shrimp. Corydoras tolerate wider params. Rams want heat and stability — fully cycled tank first.

Warm, stable, one pair
-
Step 1
Hold 27–29 °C with reliable heater
Cold snaps kill rams faster than neons.
-
Step 2
Soft acidic water or stable tap
Wild swings stress breeding colors.
-
Step 3
One pair per 60–80 L with caves
Second male fights — rock or wood territory.
-
Step 4
Don't add to cycling tank
Rams die in ammonia spikes — mature filter only.
-
Step 5
Choose tank mates that tolerate heat
Some plants/cory types prefer cooler — check species.
Common problems
Ram fading / clamped fins
Why: Stress, ammonia, or wrong temp.
Fix: Test water; raise stable heat; quiet tank.
Pair bullying third ram
Why: Extra male.
Fix: Rehome — one pair only.
Not eating
Why: New tank or aggressive mates.
Fix: Quarantine; peaceful dither fish like tetras.
White spots (ich)
Why: Stress from shipping/cold.
Fix: Heat + salt-free treatment if shrimp absent.
