There are only three fish in my tank that have names, mainly because they are the only ones distinguishable from the other schools that all look alike.
"Firefly" is one of my male swordtails, he's of the pineapple color variant with light bluish eyes. He moves like lightning in his mating/challenge displays, resembling a firefly's streaming light as they fly.
"Quicksilver" is the other male sword, his sword hasn't come in just yet and his top half is gray, his sides are black, and belly white. He also has light bluish eyes. His name is an added charm to his color scheme.
"Titan" is the solo redtail shark, obviously his/her name suits the bold disposition, and striking beauty.
Well my sons betta (actually the "family betta") is called Mr. Hanky - but i secretly call him "propane" cause to me his colours and the way his fins ripple look just like a propane flame.
