I have a 10gallon tank with 3 kribensis (1m2f), 5 (or 4?) zebra danios, 4 peppered cories and 1 dwarf gourami. I am trying to get two of my kribs to pai off and then I will move my other one to my other comunity tank along with my dwarf gourami. Two of the kribs (the male and the biggest female) seem to be really colourful and the female turn almost black sometimes. They chase the other female around but are fine with eachother and the other fish. There is only one cave (flower pot) in the tank and it is kind of big. The kribs don't seem interested in the flower pot and so I was going to buy a cave that I saw that looked like a coconut at Walmart. I just don't know if they've established a pair or not. Also, the female shows off to the male alot and follows him around.I do 2-3 water changes a week and when I do they water changes all the fish seem happier but the one female that chases around the male get a really dark red belly and almost turns completely black with the exception of her face and fins. If anyone can give me hints on how to helb them breed, I would really apreciate it.
