Anyone have any ideas if critter in photos is good or bad? Found these are multiplying in my sump. Hoping not bad thing. Most in sump baffle flow dividers between parts 2 (refugium) and 3 (return & skimmer sits), but also in first part (shrimp, filter socks & skimmer intake pump). Likely have 50+ in sump, most in dividers between parts 2/3, but also in part 1 and 3. Don't see any in refugium portion 2 of sump, but red ogo algae spins good and perhaps keeping critter from attaching to walls. Have not noticed any of this critter in my display tank, but my fish & cleanup crews seem to eat anything... Took one out and sliced open, thinking maybe egg sack, but seemed solid (but I've never before opened any egg sack, so what do I know...) Photos are same critter view, just one of photos is zoomed in hoping helps identification
