HI all, so I have four albino corys and I'm in loveee the with them. But we’ve had them for over month now and they still glass surf all time, one or two of them are down there periodically and everyone does but not nearly as much as they should? Anyone have an idea why? My water parameters are good, I have lots of hiding spots and live plants. Tankmates include two female platys and two bolivian rams. Everyone eats perfectly fine in fact once dinner rolls around the corys stay down at the bottom usually for the rest of the night. Plz help!! Why are my corys so crazy during the day!!
