Unfortunately the quality of the picture isn't that great so you can't see well but the decoration has just as many MTS on it as you can see in the sand!
Cool pix! The cories are absolutely adorable.
From what I understand, MTS come out of the substrate to the surface when O2 gets low in the tank/substrate.
Mts come out at night, I had so many I was going mad. I finally got rid of them all as they bred like mad. I found 2 yesterdaythey went by by. those and the rams horns took over my ten gallon tanks.
now my apples are going wild. wile on vacation both tanks exploded with babies, I must have a thousand![]()
