these are just 2 amazing looking german blues they are definitely a pair, both looked really healthy when i brought them, i had them in my community 3 ft for awhile then thought i might try breed them so i put them in a smaller 1ft tank, water has always been clean, up to temp etc etc so i cant see why she would be doing this, i did notice the male was chasing her around a bit and she lay on top of the sponge filter i had in there, i have now put them in a larger tank still by themselves so ill see what happens over the next few days. it would be a shame to see her go..
