So I talked to my friend and she's ok with it. Now I just need to sort out the details.
My friend's son is a huge mickey mouse fan. I am going to get him a 5g tank and full set up for mickey mouse platy as a birthday present (come this june)
He is 2, so it will help him learn responsbility (though his mom will be doing the water changes, just with him "helping"). I was doing a little research on platys, to learn how to sex them. I'll only get males to avoid breeding and overpopulation via babies. To make sure they get started well, I am getting everything needed including the tank, filter, decorations, heater, and food.
So how many male platys can be kept in a 5 gallon tank? would 3 be a good number? I can't get a bigger tank because she lives in a trailer so there's not a ton of space. Also, could I throw a couple ghost shrimp in there? or do platys not like them, or would that increase the bioload too much?
