My newest addition is a rescued blue gourami someone was giving away due to a broken tank. When I got there to collect it was in a tiny mixing bowl with less than 2 cups of water. The water was also brown as hadn't been changed in god knows how long. I found that the tank breakage was approx a month ago so the fish had been in that bowl all that time. It was also way too skinny for a gourami so had not been fed very well.
I have it in a hospital tank atm and he seems to be doing ok. One tough fish. I'll give him a week or so there to fatten up and to make sure he's healthy and introduce him to one of my tanks
