Wally World is where I get mine. Human vitamins. They're fairly cheap as well.It would be easier for me to remove aggressive ones, and if they fight at least they are the same size and could defend themselves. Thank you for the advice. Haunted55, where do you find super B complex? Tractor supply and the pet supply stores don't have it. The stuff I have been giving is an 8 in 1 and Im worried about the toxins you were speaking of.
