For the Love of Gobies

As I watched the 2 small damsels in the bag, the electric blue damsel began chasing around the bag at a rapid pace.  He seemed irritated bye the bag, although he had not done this with anything else I had introduced to the tank other than the 2 damsels lost during the cycle.  After proper acclimation and dipping, I released the 2 small chromos into the tank, and again turned out the light.  Immediately they were both under attack from the electric blue.  They zipped around the tank at lightning speeds, the chase was on.  I watched closely as they chased, and after 15 minutes of constant aggression, I decided to feed them to give the electric blue something else to do.  He always appears to be searching for food anyways, and I didn't think feeding a few hours early one night would harm them any.  Again, I watched in awe as the electric blue took turns chasing the small chromos and catching his food in between.  He had a pattern he seemed to follow, and the poor chromos were forced to find cover quickly.  It seemed that no matter where they went, what they did, they could not find a way to fend off the attack by the electric blue.  I watched in distress, not sure what else I could do.  I opened the tank, moved each rock around to a different place, hoping that maybe the electric blue was just protecting territories and caves he'd created.  This is a handy idea for freshwater fish, and I highly recommend it to my customers, but this seemed to make no difference in my tank at all.  Leaving the light out for the night, I went to bed.   Morning brought the sad discovery of one missing chromos.  When I say missing, I mean that literally.  I found no trace of it even having been in the tank at all.  The other chromos was badly chewed and his tail almost gone.
