i was surprised LA/fishybusiness didn't have them in, i'd bet they get them in quickly if you'd rather wait for those sites.
i just meant at lfs, seems like every store has them that i go to. i'm personally on the lookout for rollands and maybe talbots, but those seem a little more rare. yellowtail/azure/springers seem super common
also if you're into captive bred stuff i believe ORA breeds the springers, but they don't seem to appear online. if you have a store that orders from ORA they might be able to get you some
