I noticed my up and coming males started to produce sperm plugs, so I figured I'd start giving them the chance to make things happen. Only took a few days for this guy to catch on:
I was very surprised when I saw what he weighed in at...
I also got 2 more males that are similar size, haven't caught them in the act yet though. Seem to be in good condition, plump little things, producing sperm plugs, so I see no reason to be concerned. Obviously I will be monitoring them, but I do that will anything I got paired up anyways. Just seems to be quite small from what I have read. So I was curious, whats the smallest male you have had start breeding?
