Hello.
I have the following fish in the following tanks:
6 foot 135 gallon tank: I have 6 burundi frontosa (juvies) 3-5 inches, 2 red empress 4 inches, 1 blue dolphin (2 inch), 1 chilotilapia 4 inch range . The blue dolphin and frontosa are very slow growing.
7 foot 265 gallon tank: Arrives sat. No occupants, have 13 1 inch mpimbwe frontosa was going to put in there but can put in six foot tank instead.
My questions are:
Are knife fish aggressive (fronts are mean to eachother but wimps with other species) im looking for a fish to clean the sand and act as a distraction to the fronts (alpha is a major bully). I think you all call that dither ? I want to make sure the knife wont eat the slower growing frontosa, the frontosa are also not particulary active. They tend to find a comfy spot and just hang there suspended over an object like rockwork etc..
I have a well ,water is a ph of 8.5-9, hard water, . Will a knife live in those water parems. I used to keep south americans (oscars for 20 yrs) and my water at my new house eventually killed them. I now keep africans and they thrive. I considered clown loach but am afraid that they will not take to my water.
