i having thinking of accquiring a teacup ray to keep wth my 6 bichirs in a 2 feet tank. It is just a grow out tank and i have a 3ft x 3 ft x2ft tank wth a big arowana in it, i plan to shfit any fish that are too big for the 2 feet tank to that tank i the future. As for the stingray, i plan to put i a 4ft plastic basin, (the type that ppl use to keep koi). the thing i am worry abt is whether rays can coexist happily wth bichirs. Is my plan workable?
