My endler changes his look?

[cmhassinger]

Ok someone please tell me I’m not crazy! So the other day I notice my endler looked different and he had more black towards his face. Today I take a picture of him and he looks normal and I honestly forgot about the additional black spot and then I look at him 2 hours later and the additional black spot is back! How is that possible! And is he ok? Does that mean he is in some sort of stress? He seems fairly happy but he is in there with two young endlers and they seem to chase each other around. Not sure if they are playing or annoying each other lol the bottom pic is his normal coloring

Stress, excitement or a change in the water parameters will trigger this as well.... That´s normal...

Ok thank you! It comes and goes quickly! So I’m glad I’m not seeing things
