When you say "they do not breed together" are your referring to L95/L152 or L114/L600. If the latter, see:

From about day 12 onwards the fry became a bit more adventurous and started coming out of their hiding places to forage. On day 18 they had developed yellow spots on their body, though the tail still remained translucent. We noticed that some fry started developing a melanin pattern on the tail. This was quite interesting as we knew their parents had different tail patterns (one being the L600 morph while the other being the L114 morph).
