well this is the last of the three tropheous i bought and subsuquently lost. i have prestine water quality in which all of my other africans have been thriving for quite a while. i know they are herbivores and i have only feed them food accordingly and yet they still died one by one. for the moment i will not be trying my hand at tropheous any more because i do not want to kill anymore of these beautiful fish. i have no idea what went wrong.
