QUESTION: thank you for replying
shes eating, and shes a little chubby, not huge. but she stays at the bottom of the tank occasionally?

Answer
when they are pregnant they get massive..they look like they will pop and sometimes they go a little sqaured shape..then they give birth to about 30 fry

if she is about to give birth she will USUALLY hide and not eat..or swim round alot and not eat..doesnt sound like she is pregnant..or she may be pregnant but not to far gone :)
