I have lurked in the past, never posted before. Hi to all.
75gal planted tank with 8 silver dollars (Metynnis spp.): 4 M. maculatus, 3 M. lippincotianus, Metynnis sp.
They do not eat my plants (3 different crypts, java far, others). All decorations in tank are natural. Only plants eating duckweed (see floating corral), placed there for this very purpose. They provide all kinds of plant based and animal based foods that I provide, just not my planted plants.
