Got this amputee from Jeff Rapps as a freebie in Jan 2019 at roughly 2"-3". It seems to have reached 6"-8" today. The right pectoral fin has been missing almost completely apart from a small knob since at Jeff's (presumably removed by its kin in Jeff's tank but we can't be sure) and has never grown back at our place. An easy to feed and to comm fish so far.
