can anyone tell me if these gouramis are both male, both female or one of each, the one on the right is always a dark dark blue snakeskin type pattern.
yeah there both female, unfortunately 10g is to small for even one blue gourami, so getting another one is out of the question. unless you intend on getting a bigger tank soon.
If you are planning on upgrading them to a bigger tank soon, then getting a male would be ok. But i wouldn't get one till you upgrade them to a bigger tank.
