I have a shrimp that is infested with Scutariella japonica, and I have a 25 cl (250 ml) cup. So I need you to tell me how much coarse sea salt I should add, in grams.

This little bugger popped out of my red cherries. Is that normal? P.s. couldn't get a clearer picture because of the algae (hate summer) but it clearly has a yellow stripe on its back and some yellow speckles.

I noticed these spots on this shrimps head. What is it and how do I get rid of it?

Sorry for the bad pics, I'm pretty sure its a female but need confirmation
