So of course the internet says a bunch of different things. What's the bare minimum tank size you guys would keep a single parachromis in? Would a jag be able to live in a 75 or so by itself for a while? And, incidentally, has anyone kept polypterus with parachromis before?
Well...I had mine in a 75g. I ended up trading him in. Someone here has a picture of their 14" in a 75g. Looks way cramped. Most people would say 125g for a male and 75g for a female. I never kept Polys and Parachromis together before, so good luck with that one, but personally, I think that the Parachromis would be too aggressive, especially a Jag.
I was wondering about the poly/para mix, because most cichlids tend to ignore bottom dwellers. I've never seen a cichlid even look at a catfish before. At least not in my experience. . .
My Jag didn't like anyone. Oddly enough, he got along with an Oscar I had, but hated the JD with a passion, killed a Sail Fin Pleco and my Clarias Cat.
