I thought i would give my fish a treat so i bought some black worms. they came in a small plastic cup as i went to dip a small spoonful in i almost stepped on the cat. and in went 2.00 worth of worms that took no time to disappear into the gravel. are they going to hurt anything ?...it was fun watching the fish dive threw the mass of worms like sharks in bloody water :evil_lol:
