I have a two plecos mixed in with a few other fish. They have all been moved to a brand new 60 Gallon Tank “treated with conditioner, bacteria, and set at the right temp”. I have previously used Algae Wafers for the two Plecos in a tank and it caused one of the balloon belly Mollys to die. Is it safe enough to put 1 in the tank to help feed the two Plecos the first night they are in there without harming the other fish?
