Pigeon blood red oscars!

As long as the water is clean it shouldn't be a problem. But if the water isn't clean that when you get stuff like hlle easier at higher ph values. But I like to err on the side of caution I don't want something that used to or comes from 6ph to needing to cope with super hard high pH. I'm sure it's stressful in some aspect. May cut longevity, I don't know for sure.

I remember doing a lot of research on Oscars before getting one, and the point that struck home with me was water changes. So if you do your diligence it should work. I guess people could get alder cones, cattappa leaves/bark, etc if their water is out of whack.

But if those babies are tank bred??? ROLL OUT THE CASH.
