Goby and Blenny HELP!

[molodets]

Please some one tell me what is the difference between GOBY and Blenny? I need to buy one to clean the sand.

Different family from the order Perciformes.
Blenny = family Blenniidae
Goby = family Gobiidae
Do you have any Nassarius snails, Cerith snails? Florida fighting conch?

I got mexican snails.
Whats better to get, BLENNY or GOBY??

In my opinion neither. The type of critter you are looking for will eventually deplete the good critters in your sand bed which is not a good thing.
If you are looking just to keep your sand clean you are better off getting the snails I listed and making sure there is a good amount of flow in your tank to keep as much detritus suspended for removal by your mechanical filters as possible.
