blue flasher

all in a 120g and they hardly ever flash. i'm sure the tank size has something to do w/ it. they have plenty of room and go about their business. they may chase one another around for a second or two(my guess is that they are just establishing dominance)
they will flash @ their species, other species and even reflection. funny my pylei flashes @ me when i wear a hat and get to the tank. beats me why he feels like he needs to put a show.
In the most simple terms...it's like you flipped a switch on the fish and suddenly their colors are MUCH brighter. They use this ability to attract mates and intimidate other fish, or to show they like a particular hat...
im going to try with a net but my little guy is quick and alway waits for the food to come closer to the rocks where he just zips away..... what do you do with a fish trap put food inside?
