Hello, not sure if anyone can help but figured I'd ask. I have a 18"-20" male Coral Catshark that is nearly 2 years old, he is housed with 2 female catsharks a bit smaller than him, but they are also the same age. I've noticed the claspers on the male are pink, I'm optimistic that they will breed and hoping this is a sign that he is ready to breed. Thanks for any help.
