Orange spots do a good job. Had a dragon in my tank for a few months and he did a great job on my sand. Just a couple of problems though...with every mouthful of sand he'd swim up and sift it all over everything. Second prob was that I never saw him eat anything at feeding time. 2 days ago he died of starvation.

Rainford
 

I followed my heart (ha ha) and went with the Rainford Goby. If he ends up not doing the job... I will probably add a 6 Spot Sleeper Goby down the road.

I like the small size of the Rainford... AND they also eat hair algae. My last one went nuts for it.


Thanks!
