my first question is if two blennys can live in one tank without killing each other. i have a starry blenny and i want a lawnmower. i have a 75 gallon tank. My second question is if anyone can change my bearing on my mp40 for me. its loud and bothers me and no longer covered by warranty. i would be willing to pay if the price is righ.t thanks
