These look like potato bugs - found on the bottom of a frag disc. They have hard shells and can actually move pretty quickly. Chitons or Isopods?
These are little bright red slugs with yellowish heads. They have two small antennae and were seen on the glass, saw several yesterday for the first time. Perhaps Vayssierea Felis?:
