My HM only grew to 1.25 inches o.o I guess some bettas are just... small. I went to Petco and saw double tails with bodies the size of a quarter o.O They were seriously cute... but they seemed way too young to be sold.
No joke? They're all around here, save for maybe this one and that one, and that little group over there. But for the most point, they are way too young. They do have coloring, though. But I wouldn't be surprised if it ended up differently.
