My sisters siamese algae eater was attacking her fish so i took it to try and find a new home for it. i was looking at my tank and i saw its head was outa water, half the body, all of it! it climbed out! but when i stood up it jumped back in! has any one else had this prob? and also im thinking of taking it to a petstore and change it for a pleco.....do you think they will change it?
