    Can anyone ID this larvae that was found in a co-fishkeeper's tank?

    He has since found this in the tank too.
    My first thought was dog vomit mold, but in a fishtank?

    So you have 2 things going on there. Most likely. That bug may be a Munnid but maybe not. Usually, If you don't have a Jack Dempsey to eat these bugs they will just stay in your tank and not do any harm to your fish. Most people take these things out and don't see anymore.

    The next thing is: could that other stuff be food. That is the biggest offending problem with molds stuff growing in water with fish.

    So what are you feeding your fish?

    Hi Waretrop!
    Thank you for your response. One person in the fish forum said a drain fly larvae, but it doesn't really look like one to me.
    The second picture has been identified as a saturated algae wafer. The person is new to the fishkeeping hobby and didn't realize how much algae wafers expand when they get wet. We all got a chuckle over that. I recommended he break them in to pieces and only feed half of the wafer.

    So, one mystery solved.
    I'm still curious about that larvae.

    Bristol worm or fire worm... other looks like algae tablet after set for a while. I worked quite a few years with fresh water, marine, and reef tanks.

    Hi Beenie!
    Welcome to Gardenstew!

    Thank you for the IDs.
    We did figure out the algae tablet, but that worm still has us stumped.
    I'm not sure about the Fire Worm because it is a freshwater tank. Any thoughts?

    freshwater species namely namalycastis siolii or N. senegalensis. These are basically are bristle worms. Look them up see if they look like what you have. Let me know :) oh btw thank you for the welcome...

    The substrate is ecocomplete, used for freshwater, planted tanks. It is kind of like sand.
    I can't find the person on the other forum anymore. I guess he got what he needed.
    Thank you for the help.
