I have two African Kenyis in my tank. plus a pictus and pleco, thats all. One of the Kenyis is blue and vibrant, the other was blue and is slowly turning yellow and larger then the blue one with an egg spot. I just noticed today that the one turning yellow has little orangish yellow balls in its mouth, I was thinking they look like the Cichlid pellets I feed them (when they sink they swell up) but i didnt feed them yet. Could these be eggs possibly?
