Does anything eat (FW) hair algae?

[Delphinus]

Ok so these Ameca spendens, I'm trying to read up on them right now, is there any special considerations for keeping them? Community tank safe? What about the American flagfish? Both fish look a little like mollies to me?

Because this is a larger tank with an overflow, even with gutter guard over the overflow, smaller fish would be at risk for sump surfing (and the overflow drains onto filter floss so they'd basically meet their end) so small minnow sized fish such as smaller raspboras and tetras will not really be in this tank anyhow.
