Overcrowded?

[joeynuna]

I have a 20 gallon long tank that had 1 Dalmatian molly and 1 black molly. The dalmatian molly had 13 fry. Unfortunately, the black molly died and 11 of the 13 fry survived. So, now i have a 20 gallon tank with 12 dalmatian molly and 6 tetra. the numbers are fine but I'm concerned this tank is over crowded. A new tank is out of the question. The fish look happy, i clean the tank every week.

How big are the Fry? Molly's can get up to 3", maybe take some of your fry to your LFS?

mother molly is about 2 in. the fry are still small under an inch, and tetras about 1 to 1.5in.
