    Okay so I was starting a S. Repens carpet today and I had to use my tweezers to plant the stems into the substrate and while removing the tweezers sometimes I would stir up a worm or two. I would like to know what they are and if I should be worried.

    My tetras and Otos don't seem to mind them. They just keep swimming along.

    Detritus worms.

    Sounds like too much organic waste. These guys are not harmful to fish like other common worms HOWEVER, if you don't control the population they can take up LOTS of precious oxygen.

    Gravel vacuum carefully!

    Will cory cats eat them? I will be getting some in maybe two more weeks.

    Have not personally experienced this so I can't be certain. I also don't know of any nutritional factors of these worms. I just know where they tend to come from. Lots of waste. Your tank heavily planted?

    I wouldn't say heavily planted but it's got a few plants. Here's some pics of tank and more worms

    I wouldn't be worried, it's not unusual to have worms in the substrate, they actually help the plants by breaking down the detritus. Most fish will eat them as well.(I think this is why most people don't see them often in their tanks)

    Love the color contrast. As stated above, they are not dangerous in in a tank that size, they only become dangerous if you have hundreds or thousands of them as they do take up oxygen.

    Okay cool I'm probably sure my tetras have eaten a few if they've seen them. Also will be getting some rasboras hengli next week so there's more potential danger for these worms mwhahahah and some corys a few weeks later.

    Thanks man I'm hoping some of those crypts will start to grow and add se red into the tank.

    Hopefully I never get thousands of them or I will definitely panic lol.

    If you dont have a ton of organic matter/waste/uneaten food getting into the substrate then their population will be self limiting.
