I have 3 RES in a 30 gallon tank 2 of them are about 2 inches long the thrid is 4. They are the only thing in the tank. I would like to know if they could co exist in the same tank as a Blue Freshwater lobster/crayfish. I heard once that the lobster gave off something that was bad for the turtles. Could somone clarify this for me? Thanks
Scott
