Brain Questions
I have a red brain, not sure if its open or closed.
While i was changing water, i noticed that all its feelers or whatever were out around the rim. When the water change was done, they retracted. During the change, it did have a bit more flow to it. I have it under a ledge because i was told indirect light is the way to go. It opens up rather large during the day, but at night when the lights are off it shrinks. Also, i tried moving it to the middle of the tank, and it never opened. Should i try to get more flow to it?
