I would recommend reading and researching A LOT about stingrays so you realize the many reasons why your current stocking plans will not work. All stingrays, even the poorly named "teacup" rays get far larger than 6".This is gonna be a fresh water community tank with all kind of tetras all kind of danios about 6 guppy species, some barbs, glass fish, silver dollar, angels, NO GOLD FISH , one teacup stingray , literally small fish from 1" to 6"
