In Europe we are obvioulsy not using “blackworms” at all.
Could anybody give here the latin name of that animals and tell how to breed them?
Two inches is certainly too big for a licorice gouramy, but the adults can swallow rather big food. Larvae of midges (“mosquitos”, “glassworms”, etc.) are picked out of everything else, and they try they biggest first. Sometimes they are too big, but often they succeed. Astonishing. Nauplii of Artemia are good food, but as only food they are too small for grown up Paros.
