My Widows Not His

[DRD1812]

I have 6 black widows and one of my females is so fat it looks like she can hardly swim im expecting eggs any day now only problem is I would try and raise them but I dont know if they need to lay there eggs then the males fertilize or if its already done or if she'll only lay them if she has the right set up on the tank like plantation or caves etc.

I know its a double post if you go into the other black widows thread but I wanted my own incase people had been in there n realised it wasn't something they new and since mine is a different question u get the jist.
