Spawning Mops Floating or Weightless or Sinking

Handmade synthetic spawning mop with over 200 strands and measuring ~10" long. Can be used to collect spawning eggs or for small fry to hide in. It wont degrade and can be boiled to sterilize between batches of eggs.  Floating has a small piece of foam to keep the top buoyant  Weightless can bounce around in the tank (easiest to tuck it in decor) Sinking has a small stone to keep it in place
