Hey guys, thought I would post on this one.... I currently have one that is jus about 19 cm across. She came in super thin. Tried red wigglers... no dice. Black worms... yeh. Hit on those. While not hammering them, she does graze on them throughout the day. She goes through about 6 to 8 ounces a day. Tried grass shrimp and she just chewed them up and spit them out. Havent tried fish yet.... Beautiful fish. Been giving her large water changes and I keep introducing more black worms as the supply on the bottom of the tank dwindles. Keeping my fingers crossed!
