Hey all, so i currently have a 28l tank homing platy fish which is going fairly well although i'll be upgrading around christmas. I have a second tank which is about 15l which i use for homing platy fry and for platys giving birth. I have a 12 litre tank and want to do something with it, it's a very small tank i know but i hate knowing i have a tank that isn't in use. I was thinking cherry shrimp but even then i'd hate to just risk it being too small. Any ideas?
