Angels as dithers??

[Bderick67]

Dithers are used to calm fish down actually. When bigger fish see schooling fish acting calm they typically take their cue from them that everything is safe.

If a fish is freaked out what does it do, hide? What do shy fish do, hide?

Basically the same fricking thing, right? The use of dither fish have originally come from discus keepers, do they sound like fish that need to clam down? No they are a timid fish that by nature is shy.
