here r the pics of the second delhezi with just the bent/concave caudal fin:
the tailbone/body is perfectly straight, but for some appearent reason the caudal fin is bent to the left. i think its because of overbreeding/inbreeding. anyways here r the pics. theres also a pic of the underbelly view of the caudal fin. see how the fin is slightly bent?
Hope you can share some more clearer pictures to better appreciate them
Thanks for sharing
OT : I have a Palmas who has a bent body (begening in its middle part of the stomach started to bent upward). He wasn't like that when I've bought him.
