A 'dither' fish typically refers to a larger or more active fish that helps drive shy fish out of their hiding places, or whose presence triggers tighter schooling/schoaling behavior in other fish.

Humm! seems like differing definitions. When I first ran across the term it was concerning cichlid tanks. There it is used to describe small fast fish who give the larger fish a target to help spread aggressive moves especially during spawning when the female might be chased too much. Barbs, tetra and such. A good dither has to keep the large fish busy but still be able to get away to survive!

My thanks Sir! I don't have large fish in my aquarium. Groups of small shoaling fish, tetras etc..

Here's the list
13 rummy nose
8 Cardinals
8 Harlequins
3 Panda Corys'
2 Otos'
2 Endler Guppies (present from my daughter)

I have to say, this bunch of fish move and use all the tank to my delight
No need for a 'Dither' fish here!
Thanks for your explanation Knotyoureality

Makes sense in that context as well, even if the goal is reversed; in both cases you're adding a specific fish/fish type with the goal of modifying the natural behavior of your existing stock.

Likely the difference comes from the differing views of peole keeping different fish and tanks. I came in from the side where cichlids are the main interest. That group has a different need for dithers than a group where the fish are smaller. With cichlids it is often necessary to have a way to spread the chasing around as the fish of main interest begins to spawn. Some African cichlids will breed with just about anything that is in the tank, when one female becomes "ripe". If there isn't some way to distract the guys in the chase, one female can get beat up too badly. That's when a dither can be handy. It isn't so much that they do anything but they are just there and the chasing fish finds himself chasing something really quick and hardy that he can't catch. Meanwhile the female slips under a rock and rests for a bit.
Seems like your last item is closer to a good description of "dithers". They are not necessarily large nor small but fish chosen to stand around and "dither" until needed!

I've heard two definitions of them;
Fish that distract chasers because they're fast and can get away,
Or fish that are bold and outgoing to coax shy fish out of hiding and convince them that it's safe.
Danios can be used for both purposes, as an example.

Yeah I think you are both right in that in either case the fish used are called dithers. I know with apistos they are used to coax them out of hiding and make them less shy.

Well that's just like.........your opinion man.

Yes, same concept, slightly different application. I'd add dither fish are also typically less expensive fish that are fast enough to survive and just annoying enough to not stress the other fish out.
