For those that have kept Angels, I was wondering how caring for angels compares to caring for discus. To start off, what size angel roughly corresponds to what size discus? For example, I've seen sellers listing dime, nickel, and quarter size angels- sizes really small compared to discus. Would a quarter size angel be suitable for beginners? What would be the minimum size you guys recommend?
Based on what I've heard, angels are more hardier than discus coming to water condition. How often would you change water for a group of grow outs? I'm looking to keep them as I would discus in a bare bottom.
