I have had a Rainford goby and a Banggai cardinal in an observation tank for 21 days. Both fish were doing well, goby eating algae in tank and cardinal eating frozen homemade mix. Then 2 days ago I noticed the cardinal not eating so eagerly and just this afternoon, I came home to see it dead on the bottom. No signs of any disease to my amateur eyes. Never noticed any heavy breathing.
I guess the purpose of this post is to see what others think I should do with the goby, whether I should keep it in the observation tank for a little while longer or transfer it into the display tank.
