I remember my first batch of guppy fry. I had waited at least 2 months and watched this female look like she was going to explode and get bigger for a month as i waited.
Should have no problems getting more guppy fry now but the space will run out if you save them. I saved a few and kept them as my new adults in my 5 gallon. I had a ich breakout which killed several of my adults in my 10 gallon while back.
