The problem with too many Mexican turbos is that once they've cleaned out our algae, then they starved to death, unless you have quite a large tank that can support them.
If it becomes an issue I will trade them in for something else. My local LFS (corals galore) is very awesome and will let me trade them back in.
Thank you for the info everybody. I honestly did not know about them starving.
I guess I could also swap them back and fourth between sump and DT.
