My cambarus is sick.

Hi,
The male coosae(?) has some unknown thing in his body's surface.
I note it in the photo.

Are the parasitic microbes saprolegnia or bdelloidea?
My friend says, "The parasite is called fouling I believe."

I'm afraid if bdelloidea are in his surface.

Anyone can tell me what treatment to do?
Thanks

those are either small epibionts, e.g. ciliata, or indeed fouling with algae or fungus-like organisms (btw. `fouling´is by no means `parasitic´...)

either way, no need for any treatment, except a toothbrush

Hi,

this looks like Vorticella, it´s mostly harmless for the cray unless it gets to much, especially in the front region as it could make feeding difficult for him.
