Breeding tube?

  • We are currently upgrading MFK. thanks! -neo
sure does but from position looks like a males breading tube.
 
females will be larger and drag to the back, males are smaller and point some what forward.
 
He's been digging a lot if that helps. He's got two big holes on either side of the tank. With smaller holes everywhere in between.
