The phantom or Baryancistrus and the Hemiancistrus spfamily does quite well in a higher ph tank. I know of many ppl that keep Baryancistrus and Hemiancistrus sp especially the green and blue plantom with their african and they are doing fine. But start with bigger fish. Don't get small 2"er and expect they will survive with the temperment of african cichlids.Looking for plecos to go in 100gallon african cichlid aquarium. Need something that is not going to get harmed by the high pH and aggressive nature of the the cichlids.
