My dat keeps going very dark almost black all over?

  • We are currently upgrading MFK. thanks! -neo
Datnoids will go stable/unstable. Some worse than others. has no effect on there health whatsoever. You're good.
 
Mine change color all the time.

I only have two right now, sometimes they will chase each other around the tank and turn completely black almost instantly and be stable again minutes later.
 
Mines use to change colors. I added a lot more fish and the dats became more stable. As long as he eats, you're fine.
