We have a 6 inch pleco I call Gonzo because he goes gonzo when I'm doing a water change. He actually attacks the siphon.
We have a red and orange male betta I call Pyros. Our cobalt blue pair of bettas, the male is Azure and the female is Cyan.
All the other fish are called the "finned pack" I'm not too original.
But I am trying to think of something for a black, red and teal male betta, a silver and purple male betta and a peacock colored half moon tail betta. Ideas anyone?
