I'm just so confused as to how a black has come out of a non black group, must be the generations somewhere down the line, also noticed I have a blue/clear stripy one too haha, I think the black may have eggs? Has a low belly, I understand to have blues,reds and yellows which is mostly what seem to have come out of shimplets, and obviously wild types with mixing colours, but black! Never expected that 
lovely little things all the same, I'll keep an eye out to see if there's anymore black ones and could separate if so, be interesting to see!!
wild types most probably eh or good old yellows!
