Maccullochi Rainbow

Maccullochi rainbowfish, or redfin dwarf rainbowfish, are found in small rivers and ponds and billabongs (there is that word again) around Australia. These fish is prized by hobbiests because the males like to display their bright fins against each other to impress the females. Maccullochi rainbows grow to only two inches so these are a mid-size rainbowfish.
