With care

Verdict

78–78°F

Shared temperature

20 gal

Smallest tank

The two fish side by side

Fish	Adult size	Temperature	Min. tank	Keep	Watch for
German blue ram	2.5 in	78–85°F	20 gal	Alone or as a pair	peaceful
Corydoras (bronze or peppered)	2.5 in	70–78°F	20 gal	6 or more	peaceful

Set the heater to about 78°F, in the middle of the range they share (78–78°F).
Use a tank of at least 20 gallons, and bigger is calmer. Check the numbers with the stocking calculator.
Keep corydoras in a group of 6 or more. A big group is calmer and more colorful.
Corydoras feed on the bottom, so drop in sinking pellets or wafers after the lights go out.
Add plenty of plants and cover so every fish can get out of sight.

For German blue rams: African dwarf frog, Amano shrimp, Black neon tetra, Bristlenose pleco, Cardinal tetra, Cherry barb
For corydoras: African dwarf frog, Angelfish, Betta (male), Bristlenose pleco, Guppy, Tiger barb
