I am a semi-newbie (kept tanks as a kid), decided to start again. I have a female platy that looks very plump and I think I see the litte dark spot (I forget what its called) that may indicate pregnancy. I have a net breeder but I don't want to put her in it too early and force her to be in a constrained environment for too long. Any advice on the time of putting her in the breeder. Also, should I just take my chances and not bother with the breeder? Thanks.
