Hello. I have two blue gouramis, a male and a female. The male has been building bubble nests every now and then but the female doesn't seem to be in the mood for breeding. The female comes underneath the bubble nest, and the male wraps himself around her but she never releases eggs, so she just runs off. I'm pretty sure she is full of eggs as she is very fat and non for her fins are nipped. They both display very bright colours and eat a lot. The tank is a 180l (50gallon) and heavily planted.
