Just curious. My male cac (which is about 5 months old) has continued to develop black & red coloration on his caudal fin. It now covers about 2/3 of it. Today I noticed spots on the rear of his dorsal begining to develop. He also is developing a nice blueish color on his pectorals and dorsal. For how long will he continue to develop his coloration? Or does it continue to develop throught their lifespan?
