Fry Watch

I have at least six new fry. The are either black bar endlers or gambusia, only time will tell.

After vanishing for most of the intervening period, 2 of the fry reappeared near the water surface yesterday. This pattern of behavior and their evolving appearance suggests that they are gambusia. Currently they have vanished again.

I saw three fry yesterday, but could only find this one today. Definitely looking like a gambusia, no signed of spotting so they are either female or not melanistic.

The fry are large enough to distinguish make and female based on fin shape. So far they all seem to be standard gambusia. I am separating males and females now to prevent over-population.
