Last night, I was turning out the lights in the room with my aquarium, and my kribensis shot out of her cave with her back fins straight up and the most pronounced colors I have seen on her. Her belly was cherry red instead on the usual "blushy" color, and the darker colors were darker too. I have only had this fish for about a week, so can anybody tell me what causes this kind of display? Was she in "fight mode?" Or maybe wants to breed? Maybe it had something to do with the dark room?
