I was shocked to see how big the nuchal hump has gotten on the female Citrienllum. She recently was put into a divided tank with a large male. I kno that the hump on a male can get large...especially when in breeding condition or around other fish. I wa pretty amazed to see hers get large as well.
Here she is looking like she's "whistling" to her mate. Actually it was just good timing that caught the photo.
Side shot of her head.
