No prior to the mandarin. Idk honestly. It was fine for a few months but it didn't seem to be growing much. One day it took a ride through the overflow into the sock so I triaged and hand fed it in a breeder box and fed it for maybe 6 weeks, returned it to the tank one day I thought it was doing good but it didnt move around much in the DT so I boxed it again and then maybe a week later it passed. Idk what caused it to stop eating...
