i was thinking of gettin some pygmy corys to go in my platy tank but there only 1cm long and still quite yound, will the platies attack them? i know platys are peacefull but i jsut want to make sure.
I don't think they would but I would wait till they got bigger before you bought them from the pet store and you could ask this in the livebearer section since platys are livebearers.
Platies are pretty peaceful, but 1 cm is pretty tiny. I'd wait a little bit longer to put them together, since usually Platies don't hesitate for a snack.
