I have a 10 gallon tank that is cycled and has 3 platies in it. I've had them for 2 weeks now. I also have a 3.5 gallon tank with a single Apple snail in it. I'm wanting to put my apple snail in the big tank but I'm not sure if the platies will hurt him. they are all females and it is a heavily planted tank. I've read some stories about some platies nipping at snails but I wasn't sure if gender mattered. thoughts?
