My Flowerhorn Ivy usually has a light grayish base color with bright blue patterns. I have noticed that sometimes her base color is pretty much black then eventually it will go back to normal. Is there a reason this is happening? I checked my water and everything is in range. I have been keeping the lights on for less hours until I get the algae under control. Idk if this has anything to do with it or not. I would love to her your opinions on why this may be happening
