My Kribensis is currently being housed in a 5 gallon Hexagon shaped tank with a Rainbow Shark, 2 Ghost Shrimp, and a Blue Dwarf Gourami. Are any of these fish compatible? I know I must've screwed up, since my Shark and Kribensis are both injured. I am currently treating the tank with Melafix. If they are not, will the Kribensis be compatible with an Angelfish, a Senegal Bichir, a Red Dwarf Gourami, an Elephant Nose, and a Striped Peacock Eel in a 120 gallon tank? The Bichir is young and I'm probably going to donate him to my LFS. Thanks for any help!
