My goby keeps spitting sand on my derasa.

Will this hurt it?

 

[spspirate]

I wouldn't think so. The derasa will do one of two things, move or keep shooing away the sand off of him and in a indirect way the clam is filter feeding out any particulates in the sand.

Agreed, I think it should be fine.

It will be fine...just make sure he doesn't bury him
