Found a sweet way to personally feed my Mandarin blood worms. Found a solid piece of pvc pipe the depth of tank, and approx 5 mm or so round. Not that thick really. Defrosted my BW, put the pipe down to my mandarins hiding spot about half an inch from the bottom and tipped the BW into the pipe. They are heavier then water obviously, and sunk down the pipe almost directly to my fishes mouth. Didn't even get a finger wet. Works like a dream.... All the other fish are unawares to whats going on.
Yeah my method is really working great. He just sits in the corner pecking away till he has consumed the whole cube of blood worms. They just gradually fall from the tube. ill try to take a video if i get time next feed, and post.
