Yay Surimi shows signs of vast improvment. I gave him a 100% water change (i know i know, but the antibiotics made the water disgusting) and he is much brighter in color, swims rather like a dart, and only has a slight sign of fin rot left. I am hoping if i keep his tank very clean the rest will disappear by itself.
He is still very shy, and easily frightened, but i am starting to think either he was traumatized at the pet store, or is just rather skittish fish...
So all is good! i put him back in his regular tank, with all the normal stuff other than i changed the rocks, and he seems rather content
and Sushi has made his 3rd bubble nest, so apparently he is happy as well... yay!
