I already have it: thereās Glowlight tetras in the stocking. Honestly, itās really fine. The mystery snails and shrimp are good, and this frees me some fish space up. I think I might go with a apistogramma species, since they come in some yellows. Do a all-male or all-female group of them. Or maybe Iāll do something like a diamond tetra where itās shiny and looks kind of yellow in the right light.
