During the night my marble is making TONS of racket. What he does is a few times every night he goes up to the top of the tank, like a normal ray would do. BUT instead of going to he makes shorts bursts across the water that are around 12". While he is doing this he makes many waves and splashes water around. It is really loud. The tank is downstairs but I can hear it on the second floor. He started doing this 2 days ago. I have never seen this before and to be honest he is the best ray I have had yet. He eats lots and is always active during the day. What's he doing? My water is good I do 30-40% WC every 2 days on the tank.
