What kind of worm is this??

[jlbristle]

Hey everyone, I am dealing with small and large cell amph Dino’s and tiny white worms on the glass in my 120G peninsula. Can anyone help ID what kind of worms these are. I am pretty confident they are not flat worms since they do not seem to grow much larger than a copepod. I was able to get decent pics and micropscope photos of them. Also, I have dosed copepods multiple times throughout the last few months and they do not seem to be on the display glass as much as they were prior to the Dino’s and these worms showing up. I am dosing live phyto and spongexcel and it does not seem to increase my pod population. I am seeing a diatom bloom but it does not seem to be making a dent in the Dino’s. Any help would be greatly appreciated.

FWIW, I have seen these in my tank a couple of times to but they never stayed very long. While I have no advice for you, I thought it might be helpful to let you know that I am watching this thread and give you a "bump" at the same time. =)

The shape looks very much like a planaria flatworm to me.

*Edit: since there are so many types, this is the general shape I'm referring to...

Here is a thread with similar looking critters.... Unfortunately, no clear ID.

Totally unrelated, but isn't the spider on your profile picture a rare one? May I ask what it's called?

Absolutely! Very happy to share that info =)
This species is critically endangered in the wild but captive bred specimens are usually available in the hobby.
It's native to a small forest region in India.
Common name is "Gooty Sapphire Tarantula", named after the place it was first discovered.
The scientific name is Poecilotheria metallica.
I actually have a female in my collection and I've attempted to breed her recently. She does appear to be gravid so I'm hoping to have several babies in a couple of months =)

Thank you for the information. I myself am scared ****less of spiders, let alone these huge ones. I just remember seeing this spider once somewhere and thought they were "rare"(?) So I was curious what it was called.

Doesn't look like a flatworm to me, mostly due to the fact that it doesn't have smooth sides. @ISpeakForTheSeas

I'm not great with microscopic ID's, but I'm thinking it's a Polychaete (Bristle Worm) of some kind. The closest looking one I know at the moment is Dimorphilus gyrociliatus (formerly known as Dinophilus gyrociliatus) which is documented as being found along the East Coast of the US and around parts of Europe, but I'm not sure if it's the same species as the worms the OP has or not.
