actually the most I've seen a T. have is close to 400 to 500 babies not thousands lol..

also 3 slings is a good number to work with to get a female..

You can keep them in deli cups only till there leg span reaches half there room in a deli cup.. A 10g tank is all they need for the rest of their life..

Sounds like you fed it a cricket that was infested.. it also sounds like Nematodes tho...
