Weird Dwarf Gourami Behavior.
I have a male dwarf Gourami in a 20 gallon heavilyish planted tank.
For the last couple of days he has been hanging at the top of the tank, but them swims like he normally would.
Today, I saw him floating on his side like en he was dead. Then, I turned on n the light amd then he started swimming normally.
Why is this happenning?
