Alrighty thank you for the helpYoyo loaches need somewhere to sleep during light hours (if they choose to do so)They are also good at playing dead,lying on their sides,at least mines do.I had a single yoyo loach for a while and all it did was swim back and forth along the front glass.I added another two yoyos and they are all doing well,and growing.The lesson here is that although they look like they are having a go at each other,they are actually interacting.
You need to get that wee one some company,if it’s not too late
