tilapia buttikoferi

Hi guys Just an update on my Geophagus and Buttikoferi aquarium. 750L, 1.8m tank to recap. last month (beginning November) the Butti's paired up (got rid of the third one) and started digging themselves a breeding pit. As long as the Geos stay away from the pit, everyone seems to be getting...

So I could find literally zero info about Buttikoferi and pothos roots and whether or not they would eat/shed them. I looked for Buttis and planted tanks online, also very little info besides they are a cichlid that likes to dig and so will uproot plants. But there was never mention of them...

My tilapia buttikofferi is alone in his own tank. I noticed today he has a big deep gash in his head right above his eye, my guess is something startled him and he smashed his head into the filter intake. Im a bit worried about him, so how do I go about healing this? I just did a water change...

Can someone tell me what my ph lvl should be for a buttikoferi I'm seeing so many different levels online some sites say 7.8 to 8.6 and others are saying 6.5 to 7.0. So obviously I'm a bit confused how could they be talking about the same fish?
