I want to get a fish that will the left over food n all the junk on the sand. I don't have a top to my tank. I read that gobies r jumpers. Any other suggestions on what to get?

Iv got two watchmens and they been ok so far And are good bottom feeders. As long as they get plenty of hiding places and food they won't jump. Good luck. T
