Pinhead sized organisms on tank glass...

[Magnus]

I can't tell what they are, but they are covering the glass of the tank. White in colour, about the size of a sewing needle tip. Any ideas? Would a magnifying glass help in identifying them?

 

[neilanh]

Perhaps. Most likely pods.

 

[OniTweak]

are they moving or stationary?

Some type of pods. When I had my seahorse tank they loved to snack on them.

If they are stationary, look like little white spirals or like these white dots on my pump...

...they they are spirorbid worms, a common and benificial, if unsightly, filter feeder.

 

[Magnus]

They appear to be moving around...

 

[HoCkEyGmC]

some type of pod as mentioned before. this site could help you identify them and many other unknown creatures...

I'm thinking they are copepods, though they're very tiny. I feel bad everytime I clean the glass, it's like Godzilla rampaging in Tokyo lol.

I'll have to try and aquire a magnifying glass.
