At one point in time back in the 1990's and early 2000's I used to frequent Fraser Aquarium and I was able to buy live Brine Shrimp and Tubifex worms. The brine shrimp were large and the fish loved them. The tubifex worms used to clump together in a ball inside the plastic bag and I used a cone feeder in my tank to feed my fish. Even my clown loaches would come out of their hiding spots and eat from the cone feeder. Does anyone sell these things anymore? I doubt online sales would work due to lifespan but does anyone locally raise Brine Shrimp or tubifex worms.
