They were greyish in color, with white legs. I could easily see their guts at their back (Since the black color of the guts are so clearly show out).
I did try to add air stones, small stones, few small rottening plants from my own tank, use fish tank water, to fill the
1 gallon tank. Since they were going to die for dinner anyway and I see a lot of them, so I take one out and put it into the 1 gallon fish tank(yes I know it's really too too small of it
)... at first it looks quiet and don't move around much but only moving its legs and 'touch' its head once in a while. Then maybe 2 hours later. It moved so much that seems it hurting itself... but after 2 more hours, I don't want to keep it as it seems suffer from lack of space... that shrimp swam fine though...
But I am quite sure as fishkiller_nomore said, it gonna surfer sooner or later, since I know nothing about shrimps
I am living in a place called Macao, south east asia, I did search for gulf shrimps, yes seems like maybe its them?... not sure
