Not new to keeping fish but new to this forum. Have a planted 75 gallon community, a 72 bow front goldfish, a 10 gallon for a betta, a 10 gallon for a couple pea puffers and a 120 with discus and a stingray. Looking to upgrade from the 120 to something the stingray can live in forever, so I don't have to sell her within a year or so
