I did on these ones, but I honestly dont normally feed them feeders I was at the pet store and said why not spoil them a lil its always fun to watch... so i asked for 25 she gave me like 35 of them and they were gone by the next morning after i put them in
QT would be too put them in a "Feeder Tank" and feed them anti-bacteria and anti-parasite, and leting them go in the tank for a while. With the mass production of those feeders carry alot of Problems.
