I have these worms I don’t know what they are they dont really look like planaria to me I figured they all seem to be here so maybe my trumpet snail had babies but they don’t look like they have shells. Are they harmful and should I remove them.

Yeah this is a picture I just took the other one was from a few weeks ago and his shell is still growing consistently thank you very much me and my mom were getting a little worried because the internet didn’t have much to say. One again I’m so grateful for this community.

So this is Fin my second blue mystery snail I bought him a very light blue and now he’s growing darker shell he moves around good he’s growing she’ll quickly and he seems happy to me so I imagine he’s fine and it might be different mineral compounds in my home water because we do have well water but I’m not sure.I also have another mystery snail I go whose shell looked cracked and unhappy he’s brown and his new shell looks really pretty and healthy but still similar to the old shell color as before. Any tips or tricks or things I may be doing wrong are appreciated.

This is amazing that there is such a helpful community here thank you guys so much🥰

Wait so I thought my trumpet snail had babies but I also thought they looked a little weird to be trumpet snails so are these bladder snails

So the consensus is bladder or pond snails but we don’t know which. And I have no idea how I got them because I haven’t added new plants for months. The white pieces in the moss are broken egg shells because my mystery snail had some breaks and cracks in his shell when I got him and the stuff on the top is where my filter pushed the dried bloodworms I feed along the side of the glass and it gets stuck during water changes.

Their all over both my aquariums. I took photo and asked my local fish store guy and he thinks they may be bad mystery snail eggs because my mystery snail was letting this gross green stuff out a few weeks ago I’ll attach a photo but I don’t know if they were eggs or not. Other than that I have guppies but only in the one tank and the other only has trumpet snails. I think they may be copepod eggs but they have been around way too long for that I think so I have no idea. Any help would be appreciated.
