My friend has what he thinks may be a pair of C. Saxatilis. The only problem is the one he thinks is the male has a very small spot of "dirty" or off color pink on its belly. The female has a lot of the pink and it is bright and not all mucky like the males small spot of pink. I told him I thought it might be 2 females. My question is can a male pike develop a very small spot of pink on its belly like this?
