I just moved from a 60 gallon to a 90 gallon dirt and the process took 3 days (60 started leaking) so there was deffinetly some unfiltered water left in the 60, both the 10 gallon tubs the fish were in had sponge filters, and the canister filters did not get turned on all 3 days. So I find this worm in the substrate from the 60. Is it a tubifex / sludge worm or should I be concerned about parasites? Anything I should do? This worm has been removed.
