Yellow Cucumber?

[helpme74]

Ok I went through 5 diamond goby and I need something to clean the bottom of my tank. I have fine sand. Someone told me that a Yellow Cucumber will clean the sand very good. Does anyone have one? Let me know what you think about them. And also if they die do the put poison into the water. My 75 gallon tank has been up for 2 years and the gobies jump through my egg crate.

yellow cucombers are filter feeders they attach to a rock and filter the water. what your talking about is a sand sifting cucumber, they come in various colors, some may be yellow. mine is black and it does a awesome job. i heard they if they die it can crash the tank but i dont know if thats a rumor or not.
