Got a pair, total length is about 2.75". Sold as Percula. One is a little lighter orange, the other is an absolutely beautiful rich orange. The two hang out together and swim side by side. Might be hard to see, but the dorsal fin is rainbow shaped, not higher in the back or the front that I can tell. The dark margin between the orange and white is very thin at this point. Are they too young to tell?
This is the reflection in the glass, not two fish.
