Earthworms in Shrimp Tank?

[Mreden]

Hi all. I had a small shrimp tank set up for about 2 weeks now. The water and shrimps have been stable.

So I went to a LFS to get some new shrimps in the afternoon. When I came home last night. I found that my tank was crawling with earthworms?

They are not the type of white worms which some of the Bros mentioned here. They are brown in colour.

So is it safe to to leave them there?
Some of my shrimps are berried so I am not sure if I can change the water.

Thanks alot.

how they look like ? flat or long and they crawl in the mud ??

Long. They look like the attached picture which is an earthworm.
The longest one I saw so far is about 1 inch.

i tink those are not earthworm... they should come from your plants.. especially those dead log and sponge kind.. they are a nuisance.. lucky for me, my gravel are only 1 inch deep.. i used chopstick and removed each and everyone of them .. LOL... now i soak all new plants with parasite removal agent before introduction...

i have tat too in my tank, diff to remove or zippon them when wc.. they run super fast.. wanna catch them, they already dig into soil liao..
