Linda4fish Posted July 27, 2022 Share Posted July 27, 2022 (edited) Saw these squirming around my snail tank this morning I’m not sure what they are or if I should be worried? Edited July 27, 2022 by Linda4fish Link to comment Share on other sites More sharing options...
Chick-In-Of-TheSea Posted July 27, 2022 Share Posted July 27, 2022 Could be detritus worms? (Harmless) @Colu @Odd Duck @nabokovfan87 1 Link to comment Share on other sites More sharing options...
Odd Duck Posted July 27, 2022 Share Posted July 27, 2022 Yep, looks like detritus worms. Harmless fish food depending on the species of fish you’re keeping. 1 1 Link to comment Share on other sites More sharing options...

I was given a 10g with fish that had never seen a live plant and it was overrun with detritus worms. Link to comment Share on other sites More sharing options...
MattyM Posted July 27, 2022 Share Posted July 27, 2022 (edited) These just showed up in my tank the other day after adding a lilly bulb and a new plant. They may have been in the soil the bulb came with, as I split the plant into 2 tanks and the one that got the bulb has the detritus worms, even though I rinsed it well 🤷♂️ From what I've researched, they are harmless, and like to eat, well, detritus (dead plant matter, algae, etc). I don't have any fish yet, but others say fish enjoy snacking on them and will keep them in check. Once food in the water column is gone, they might retreat to the substrate. I plan to cull a bit with a glass wipe and small water change. Edited July 27, 2022 by MattyM grammar Link to comment Share on other sites More sharing options...

Makes sense because they are free-swimming whenever substrate is disturbed (and sometimes when it's not).

BeeD Posted July 27, 2022 Share Posted July 27, 2022 I've had some show up years after the last new plant/animal entered the tank. It coincided with an overfeeding of dried tubifex worms, and then I think the gourami and the serpaes obliterated them. I think I can support what everyone is saying with some anecdotal evidence, they seemed harmless to me. Link to comment Share on other sites More sharing options...

(Harmless) @Colu @Odd Duck @nabokovfan87 Odd Duck is probably right. They look like they have a flat body shape to me though. Reminds me of that terrifying photo you sent me in my thread from some store or something with those giant worms in that tube. Link to comment Share on other sites More sharing options...

nabokovfan87 Posted July 27, 2022 Share Posted July 27, 2022 That other thread I had mentioned to verify it wasn't planaria. It looks like those (rhabdocoela) I can't tell if it's just because I'm not awake, haven't slept, and no coffee yet! 😂 ....or if it's detritus worms. SO..... to answer the question with "how" they show up. 1. Introduced on accident somehow. 2. They were always there and conditions let them show up. I would be sure to verify your equipment, make sure the impellers on all your pumps are clean and working at full bore. Also, add an airstone if you don't already have one running in the tank.

There were just too many. It was ridiculous. 1 Link to comment Share on other sites More sharing options...
nabokovfan87 Posted July 27, 2022 Share Posted July 27, 2022 I just want the fish healthy and happy. I am fine with "an ecosystem" but just want to make sure I'm paying attention to things that can affect me. Snails, algae, worms.... I just don't want things to take over and try to keep things in balance a bit. 1 Link to comment Share on other sites More sharing options...
Brandon p Posted July 27, 2022 Share Posted July 27, 2022 I do think you do need to watch balance. A balanced aquarium is goo but if I see an explosion of one thing be it snails, detritus worms,limpmets(I have never seen explosion to worry about other than looks with this), algae or whatever it’s then I start to think what is causing this. With detritus worms the first thing would be to much food or lack of vacuuming(not always possible in all tanks due to reasons. Plants, moss, or something else.

Biotope Biologist Posted July 27, 2022 Share Posted July 27, 2022 Looks like leeches. Note the suction cup foot. And flat body shape. That’s a tell tale sign. Could be snail leeches, but I don’t have experience with these to identify correctly. I’m still fairly certain they are a leech. Unfortunately I think these are hard to get rid of as most medications that target them also target snails. Perhaps @Guppysnail has experience? 2 1 Link to comment Share on other sites More sharing options...
Guppysnail Posted July 27, 2022 Share Posted July 27, 2022 (edited) I agree with @Biotope Biologist they do look more like leeches. The only thing I know that works without leaving harmful to snails residue is to salt the tank. Remove inhabitants and do a coop level 3 max salt. This will harm your plants. However soaking your plants weighted in plain seltzer soda in the dark 9-12 hours then returning to a container of aerated water while the salt is in the main tank will kill off the leeches without harming the plants. Leave your snails in a bare easy to see tote or tank for a week or two and observe as tiny leeches can hitch hike under the shell. I would stir the gravel so no pockets escape the salt. Do huge water changes to remove the salt also stirring the gravel. Two weeks of no leech sightings in with your snails and you should be good to return to tank as normal life saving all plants and not risking snails with harm chemical medication. Anything that kills leeches and worms harms snails. They have the same body makeup. I hope that helps. Here is the seltzer article as to why it works.
