It's cool eh? I was happy that my largest loach won the "dominance fights" because he has the most diverse pattern I've seen on a loach. Saddle on both sides, partially orange dorsal fin with droop at bottom of that stripe, a dot on one side, and a half moon on the other (with a small spot starting to come through).
The interesting thing I've found about spots on clowns is that they start off faint and gray then become more pronounced as the loach grows. There was no evidence of a spot when I bought him until later... I thought it was a disease at first!
