Update! Sorry its been so long!
Well the screen is growing but it's also being groomed all day. I have cleaned it only once. Mainly b/c this female Molly (who killed the two males) has kept the screen so bare there is nothing to clean...
So it's just the one Molly in a 30 gallon, water is perfect, and well... Not just one any more...
About 15 fry, and she getting ready to to drop more...
