Large white dots everywhere

Recommended Posts

Hey,

 

Wondering if anyone knows what these are. They are everywhere all over any algae in the tank and glass. They aren't spiropid worms as they move around like pods. However they are around the same size as a pod but they are more white and very very round. Pods seems to be more slender. Not sure if they are a pest or not.

 

Any ideas would be great.

kind of look like maybe acoel flatworms. Those are more algae eating type but are very prolific. Would need a clearer picture to get a true ID or even a microscope picture. Here is ones that I have been siphoning out of my tank. Both the same thing from a little different angle.

Thanks for the reply. They don't quite look like that though. They are round and move very quick like pods do.  Don't quite have that flatworm odd oval shape. I only have my phone to take a picture of them unfortunately.

Also for a scale reference they are roughly the size of the pods you have on the glass in bottom left of the second picture. Just quite a bit fatter and rounder.

i would have guessed they were some sort of pod, especially if they're fast-moving, but only seeing white dots makes them impossible to identify. copepods are less long than amphipods. or maybe - rotifers of some type?

 

i said fish snacks because my fish won't let anything float around uneaten except pineapple sponges that get loose.

Oh ahaha yeah. I can't say I've seen anyone eating them but who knows. I've got a new pic. The red circle is one of them next to what I would call a normal pod. Blue are other normal pods and green are these big round things.

😛 I defo do not have those sort of tool available to me! I did consider they may just be another type of POD but I wasn't sure and thought someone might have seen something like this before on here.
