I have been posting a lot of threads here lately, with my gouramI issues, and setting up a new 75 gallon tank so bear with me. I have done a lot of research on the dwarf gouramI indovirus, but I'm confused. My gouramI just lays on the tank bottom, and does not move, except to come up for air, or to check out food. Although he does not eat, so I ordered some hikiarI pellets for him to try. What I'm trying to figure out is in between his two barbs that hang down, I think that is what they call them on the front of him. There is a black stringy looking thing hanging down, do not know how else to describe it. I took him out and looked at it, but it is attached. I tryed, but could not get a good picture of him any ideas.
