Dead spotted goby
Recently my sister lost her spotted goby. He seemed fine for the most part except for one day. She woke up to find him dead, or just about. There was no sign of a deesiese like ich or anything like that. The only thing I seen was discoloration of the gills and his underside. He was mostly white, but when he died his underside and gills had turned a strange colour yellow. We checked the water after he had died and everything checked out. There isnít much in the tank, a starfish, a shrimp, and a little pink and yellow fish, forget what they are called. Any Ideas? The only thing I noticed was that she never had a heater put on the tank, the water was about 24c. Also, I donít know if this makes a difference, but she has two actinic lights on instead of one actinic and another "daylight" one.
