White dots on glass

[Alex10is]

Hi guys,

I finished cycling a tank and added 2 dwarf puffer fish to it. A couple hours later the glass was filled with white dots. What is it?
Thanks

Do the dots move at all? Do they kind of slither across the glass?

Yeah they do

 

[Alex10is]

They kind of sway in the current but aren't physically moving

Do they look like mini little sea anemones?

 

[Alex10is]

Yeah they do

They appear to be hydra.
