Very helpful thank you. I love my cories so am glad to hear that it's more inter-species territorial.
We do have a blue light. currently it's set on a timer for the white light for day, then basically cuts off at night. Does the fish need the blue? or can we just let him have his time in the dark to do what he needs to do? is the blue basically for us in case we want to try to spot him?
Thanks a ton!
