I am thinking of a long, narrow, squat tank with some starlight bristlenose plecos in it, and a nice betta in there. The thing is, to thrive and breed the plecos want blackwater conditions, very soft and acidic. How are bettas with that? My last betta, I didn't give much though to soft/hard, acidic/alkaline water, only ammonia etc. I must have done alright, I guess, because he lived a good few years, but I don't want to put one in water that's not suitable.
