Have you tried putting a couple live snails in a trap as bait to see if you can lure it into the trap?Yes, and two mantis shrimp… trying to figure out how they died being covered by a huge slime blob is how I found out about the worms. The biocube is covered in algae since I can’t put anything in there to take care of it. If you see it again and it doesn’t look like an orange millipede, it’s probably not an oenone fulgida.
I haven’t tried to put anything in the tank in years so maybe they could have died out but not likely. I think I’ll have to move all the rocks and sand out into a seperate empty tank and test a snail in the cube
