platy sex ratio issues?
 
hi, looking for a bit of advice, also new to the forums though I frequently browse here for info :-D
I have a thirty gal aquarium with 3 male platies, three guppies, 6 dwarf cori's, and two african dwarf frogs. I would really like to get some females for my male platies, but I worry about overstocking? usually I have heard a ratio of 3 to 1 female to male ratio is best, but I really don't think I could add nine platies. could I add three females without an unbalanced sex ratio or overstocking? how many would you suggest? or would you think my tank is stocked enough as is?

Hello and welcome to TFK :-D For the size of your aquarium you should be fine with adding the female platys, either six or nine. You can get away with doing a ratio of 2:1 female to male, although 3:1 would be better. What type of filtration are you running on the tank, and also do you have any live plants in the tank, if you do they will help with the filtration. A neat tool that some use when trying to figure out stocking is a calculator on aqadvisor, it does not take into account if the tank is planted or not, which will add additional filtration, but it can help in giving a general idea.

i'm running an aquaclear 50 with bio media, floss, and two sponges. it is planted though quite lighly and all my plants are new and small, about 6 dwarf sword bunches, about 6 Cryptocoryne wendtii that are still small, two giant marimo balls, 5 small. a small amount of pellia, about a 5cm by 5cm of weeping moss, plus a bit of java ferns.

With the filter and the plants you should not have any problems with adding the female platies, either 3:1 or 2:1 ratio would be fine.
