I've ordered from Ken's several times. Various for my cichlids, cats and pleco's, TFB's and red hooks. Never had a problem with anyone not eating them, and as mentioned the price plus shipping still can't be beat.
you cant beat the price, but i would agree with the person who said order a little bit of everything and test it out
all of my smaller oscars and pbass will eat any of the pellets, but thats all they've been offered since i brought them home.
but my 3 larger bass and aro grew up on hikari massivore and whatever kind is in the red bag (hikari cichlid gold?) and i have a hard time getting them to eat ANY of kens pellets.
