Is that microglanis iheringi or something else with the same common name? I only ever see the tail of my MI, he's squeezed tight into a tunnel in a piece of wood, and only comes out after lights out.
I don't really know. I think it is a jelly bumblebee cat which is one of the three color forms of the South American. A picture of the whole fish is coming soon so keep watching this thread.
