Engineer gobys. They dont clean the sand by sifting, they dig and i guess that cleans it. They get pretty large so i hope your tank is big enough for 2!
 
How large? I have a 90gal. Should I have gotten some other goby?
 
Well i have 1 in my 66 gallon an he is about 9". I dont know if 2 full size engineers will fit in a 90, but yours are small and should be ok for a while. I think max size is around 1'
 
Uggh. Sounds like I got the wrong thing to clean the sand.
 
Thought the name was something with "eel" in it.
 
No trust me, it will clean the sand alright. My sand is perfectly clean because he is ALWAYS shifting sand and there is never time for any cyano or poop to collect in one area because of his constant digging. Your sand bed will have mountains
