RE: Lampeye Notes v2
Hi Brian,
Yes, Riv Agilae have several color patterns which they seem to use to
communicate. They can go from very light to black. They can turn blues and
reds on and off at will both on their bodies and fins. I have seen one male
swim up to another and turn bright blue. The other responded by turning
black. The fish changed colors to different patterns a few times over the
course of a few minutes. Sometimes two males will change colors to match one
another other times one pattern seems to be a reply to the other. They also
seem to have control over their iridescence.
Best regards,
~RJ~

All,
I have been observing the display antics of my Plataplocheilus Sp. aff.
pulcher this evening and noticed something I've never heard mentioned before
with these fish. As part of their display behavior they flare their gill
covers and extend a "throat-flap" that drops below the mouth and gill region
very similar to the way Procatopus males show off for one another. In
addition, they have the ability to "flash" a tiny metallic-blue spot at the
tip of their upper jaw, like a miniature spot light. I have seen a similar
ability in my male L. kassenjiensis where he "flashes" his blue body at
others of his species. I wonder if these behaviors are similar in function
to how male Rainbowfish interact, when they "flash" portions of their head
regions at each other. Do other Killies show this ability?
Cheers,
