Fish Fanatic
i have a 75 gallon community freshwater tank with sand that is about 1.5 inches deep and I am worried about toxic gases building up in the sand. I have heard about the Malaysian Trumpet Snails but want something else that is a little better looking. I have thought about the Blue Lobsters but am worried about their aggressive behavior. The smallest fish I have is a tetra that is about 1.75 inches long. Is there anything else that would keep the sand stirred.
