Care and Environment
Proper care of the Ruby Rainbowfish involves attention to tank size, water parameters, and environmental enrichment to ensure a healthy and vibrant fish.
What is the minimum tank size for a single Ruby Rainbowfish?
A minimum tank size of 40 liters (approximately 10 gallons) is recommended to provide adequate space for swimming and to maintain stable water conditions.
What are the ideal water parameters for Ruby Rainbowfish?
