Sea cucumbers?

[tomreefer]

What is a good sea cucumber to clean sand bed? I have a Red Sea Max 170 and want the smallest one. Tiger tail? Pink Hot dog? Caribbean ones? black ones? do they eat cyano? bugs from sand?

Thanks

The "smallest one" will process very little sand and even the big ones don't do much... Get then for the cool factor and nothing else..
I have 2 tiger tails each the size of a hot dog in an 80g and they really dont do much work stirring up the sand besides like a 6" radius around their cave..

I put one in for my grandson and is just by my overflow and has not moved in a week he just likes it there

I would go with Tigertails. In my experience they cause the least issues.

The black ones are more active and mobile than any others. I've kept them in my tank always with great results.
