As said above, the Sleeper Goby will make a mess! Please do not buy one if it will end up annoying you...I hear of people all the time "getting rid" of them because they spread sand around a lot. Not really fair since its just natural to them. I love mine, he keeps the sand very clean and its not a big deal to me if he makes a bit of a mess :)

This is an example of him cleaning the sand:

Thats a great shot.:smile:

I ended up getting a dragon goby......he is working really hard at sifting the sand and he just stays at the bottom and doesn't spread the sand everywhere......thanks for the help.

When they bigger it will take mouth full of sand and sifted it above the rock, covering everything. All so they can move all the sand from one of the tank to the other side. This is what my 3" dragon goby did in my tank.

My dragon spreads it everywhere. The signal goby neatly sifts it over his fused fin, which is nice. I think in the future I may choose another signal rather than dragon for a sifter.
