Quinn - I just love him, period. He's the most monstrous betta I've ever owned (I measured last night, we're approaching the 4 inch mark), and he's got such a unique personality. Everyday when I come home, he charges at the glass, puffs out his gills and blows me a bubble, then stirs up the Cory cats so I can count them. He always swims around the tank with his fins spread out, I've never seen him clamp his fins since I rescued him, even with his chemical burn.
Boba - Boba is just a little ball of hate. He's tail biter, and never stops moving when I'm in the room. He doesn't do anything in particular, but I always tell him not to burn the house down or kill anyone before I leave. XD
Möbius - Even though he's newly adopted, he's already become used to the household and developed his own little quirks. He cruises the back of the tank, staring down his reflection and flaring anytime the blinds of my window moves. Whenever it's time for bed, he either sleeps in his piece of driftwood or lays down in the little "nest" he's built in the gravel by the glass closest to the tank. Then he follows me up in the morning and paces back and forth in front of the glass to see if I'll feed him. Once his fins go back to normal, he'll be such a spectacular fish to behold in the mornings.
