Report Red Edge and Red Skirt? in Isopod Forum Posted October 9 22 hours ago, Rgrant said: Have a friend who says Red Edge and Red Skirt are the same. When I looked it up, one site states both are Cubaris and another Red Edge are Cubaris sp. and the Red Skirt shown Porcellio scaber? Just a little confused here. What is correct? For nearly all intents and purposes, the "Red Skirt" and "Red Edge" isopods are both referring to the same Cubaris species. I have not seen the Porcellio scaber "Red Skirt" circulated around really at all in the hobby yet, so 99% of what you see under that name should be Cubaris. Always best to ask for pics/species confirmation either way if you're trying to acquire some though.
