You guys have me wondering now......gonna have to check my tank when I get home. I have 5 assassins in my 10 gallon (had like 300 mts!). MTS are still having babies, but are in much better control now. I have seen the assassins doing the McNasty, but never checked for eggs.
10 Gallon - Planted with Endlers and Red Cherry Shrimp
