Do a water change and try to get as many of those as you can out!

I would do a big water change bump the heat up to 85 and add salt 1 1/2tsp per 5gls

They look...look, not sure... like Hydra. They are Cnidarids, like Jellyfish and Anemones, and will really only cause a problem to egg layer fish fry.

Wow, looks like you have a lot. Last pic has them all aound your shot.
I would also drop your feeding schedule (for the time being atleast) and if you use pellets, I have noticed they attract more of unwanted parasites (crap in general).
