Reply To: IDing rainbowfish (species and gender)
It’s interesting that you all are interested in this fish too. I wonder if people who like Celestial Pearl Danios also happen to like the Dwarf Neon Rainbow Fish (Melanotaenia praecox). I happen to be a big fan myself and have 6 of them (3M, 3F) in my main 20G tank as the dominant school.
There’s something about their silvery blue scales, red/yellow fins, and their swiftness and grace. Remind me of dolphins.
