Okay this is from a while ago.

I was cleaning up my tank and doing a water change when a MASSIVE worm came out of the gravel... I about broke the lid getting my hand out of the water and jumping away from the tank. It was a Night Crawler that I had left over from a fishing trip and had tried to feed to my fish at the time, it was like 4 inches max then. I put my hang in a grabbed it out of the tank at least 16 inches, very cool. My mom thought it was a snake at first (which she was fine with) then she heard it was a worm and freaked out. :ROFL:

Any way I have a bunch of earth worm left over from a fishing trip and I have some Q's.

Are they in any way unhealthy for the fish or aquarium?

Do they help clean up waste in any way?

How big do they get?
 
Well apparently they do, and they seem to like it.
 
I would be scare too if I saw that. I thought they live in cold water and cannot survive in warm water. From what I hear worms are scavengers. They eat dirt and suck the nutrients from it then it pass through their system.

Pretty sure nightcrawlers are 'dirt' dwellers.


Well tell it to the one that was in my tank for over 3 months.
 
Sorry allow me to correct myself it is a Earthworm, not a night crawler. This is real, there was a HUGE worm in my tank I really don't know how the worm was living in the tank but it was, and the water temp was above 70-90 F I can't remember what time of year it was.
 
im surprised it lived so long as well, i don't think earthworms have any benefit but being extra tasty and good for your fish, they are only beneficial to soil, by eating dead organic matter and keeping the soil open for aeration, maybe if you had a sandy bottom, it was doing that, but its just crazy, it should have drowned, thats why they come out of the soil during rainstorms
 
This is amazing. I would think aquatic earthworms would be in demand since they would live until eaten and not decay in the tank if missed. I've had earthworms die and had to fish them out. Narsty.
