While I did not have them long enough to give a conclusive "yes they will be fine" answer, I had a group of ten youngsters that grew up with me early last year until mid summer, when they started to display breeding behaviour. I was a bit gutted when I had to sell these and my group of 11 young Brochis splendens (to the same buyer), but it suddenly dawned on me that my tanks were going to become too stocked with bottom dwellers, leaving little capacity for upper water fish.
My tap water lies in the pH 8-8.2 ballpark, I do tend to use a lot of bogwood in my tanks, which helps to drop the pH perhaps upto 0.2 pH degrees.
