Well as far as i know they have never been spawned in captivity...
Could be a tumor. I am not sure.

btw, What is your substrate? Looks really different!

it is about 2 1/2 inches

I am thinking female... just need to know for sure, and any hints on picking out a mate?

I have noticed they all have unique dorsal markings
One of the new ones has a dark band and a black spot, and the one I have had for a while just has a spot.

give me stocking ideas and creative criticisms on the decor.
