So I have a tomato clown in my tank. I picked him up for my bubble tip nem. The second I put the tomato in he went right into my nem. My BT nem is on the top of my scape. 2 months ago I added another nem. I added a rainbow nem and he made a home at the bottom of my scape. Now today I noticed my tomato going from the top nem to the bottom one and back to the top. It seems like he is living in both nems. Has anyone seen this before?
