My albino does it too, i think its courting. Me endi just sits their and my big sen Nessie nips him when he gets on her nerves.
That is pretty weird. I've never tried doing a blue light on my fish to see if they would react. I have a feeling eventually the pearsei will figure there is no danger and start eating. Enjoy the peace while you can, lol
The fish must have had a traumatic event in its life involving blue lights.... possible police chase? Alien abduction? Bad KMart Blue light special experience? lolHis probably sensitive to blue light. Lolz
