I've recently noticed a similar kind of squiggly white nemotode in my RCS tank which had me worried. I was going to stop feeding for a bit but then this morning I watched my biggest RCS catch and eat one. I didn't think that shrimp actively hunted detritus worms but I swear that's what happened. Hopefully my homicidal RCS will take care of them for me!

Cool! I wish my amanos would eat these things!

I don't feed my amanos. They just clean the tank. In 4 weeks I have given them algae pellets once.

Grabbed a pic this morning of the worms in the sub since they aren't moving as fast and I could capture them in a pic a little better.

You can see how the front is bigger than the rear half.

Nematode or detritus worms..beneficial to your tank. They are cleaning up crap in your substrate. Parasitic nematodes are not common.

Ha! Nematoda is the name of a complete phylum, so yeah, there are quite a few different species.

Although there are a lot that are parasitic, there are a lot of free-living ones that are beneficial to ecosystems.

Although, based on your sketches, I'm not sure they are nematodes. I think most (all?) nematodes are fairly even in thickness their entire length. Also, nematodes can't 'stretch' like an earthworm can, they can only move back and forth (swimming in an 'S' shape like a snake). If those worms ever stretch/contract, they are probably something else (annelid, maybe?)

I'm kinda curious as to what they actually are...

Yeah, after watching them for a week now I feel like I know them lol.

They definitely have a "head" and they stretch and contract when they burrow and even crawl on top of sub.

Once they go "airborne" from the bottom though they do the "S" squiggle but seem to go wherever the current takes them.

Like a house fly, they don't seem to know or care where they are going it's just random swimming until they fall into a plant at which point they wiggle free then squiggle-swim some more.

My No Planaria arrives in the mail today.

As stated last week I ordered No Planaria and I decided to dose it.

Followed instructions. Took carbon out of my hob filter, which left the sponge and my Seachem De*Nitrate media I have in a media bag.

Its chalk white...looks like chalk. I didn't realize it had some clumps.

I just dumped it in tank. Water is pretty cloudy and I imagine it will stay that way until the end of the 3 days.

Some of the clumps are being investigated by the amanos.



Been 15 mins. Still seeing worms.

Very hard to tell if they are behaving any different because they were erratic to begin with.

Will report back in next few days my results.

Day 2 of 3 day treatment. The worms are still here although I have seen some dead ones caught it hairgrass...



Today I shook the powder up beforehand in a small tube with tank water. Yesterday some clumps fell to the bottom and this method no clumps.

I can't tell if this will work on what I have. I imagine since it is a 3 day treatment... it's not supposed to kill worms on contact but through prolonged exposure.

So it has been 24 hrs. I just dosed 2nd out of 3.

Do see some dead but also see more swimming still than I do dead.

Could be shrimp eating dead stationary worms since they can actually catch them or this stuff isn't really working.

Can't tell. No shrimp deaths or odd behavior from them.

Will report back on this treatment tomorrow after final dose.

I'm really curious as to what they are. Since they were 'stretching', they aren't nematodes. But that still leaves a lot of other types of worms.

Hope things work well, and if you find out anything more, please post.

Will do.

I'm about to dose 3rd and final dose. I still see them swimming so I feel like No Planaria has not worked.

Nevertheless I am going to finish off the treatment.

The design of the worm worries me.

Looks like when I get fish I'll just have to hope for the best and hope they eat the worms with no problem.
