right now b/c the tank is new i am keeping them feed so they stay off each others fins once they have been in this tank for awhile i will not feed them as much so i can get that desired frenzy when they feed i do have pellets but they do not seem interested in them as for not feeding live due to disease i am not worried (i know that sounds bad) but i wan t them to eat as much live as possible it is what they would have done in the wild and what i wish them to do 9its a matter of personal preferance) i may try again to get them to eat the pellets but like i said they do not seem to care when they get droped in the tank but i will change there diet from time to time to keep them as healthy as possible i WILL NOT feed them the same thing all the time for i know that that will more then likly cause problems in the future as for the fillet i have allready thought of this but have yet to try it ,but i will
