Drago was a Petsmart rescue, too. He was such a tiny little thing, and he wouldn't flare for me, no matter what. There was this huge red crowntail who wouldn't stop flaring at everything, and I almost got him, but Drago was looking at me so sadly from his cup, I knew I had to take him home. I gave him a tough name (after the Russian boxer in Rocky) because he was such a little guy, and he's really blossomed for me!
Drago is so chill haha, I've never actually seen him flare and puff out his gills and whatnot. And he never builds me bubblenests lol. But I think that's because every time he tries to start one it's water change day and it just gets destroyed anyway. :(
But I ramble... handsome boy, congrats on the bubblenest! lol
