Does this work in freshwater?

[J. H.]

I read about this and heard it works. Go online and get a picture of the aggressive fish (try for the same size). Tape it to your tank (photo side in) and put about 10 of them on there...... The aggression will stop, the picked on fish will be ok. Every 2-3 days take a few photos down and then all should be fine.

I haven't had to do this but think it would be fun if needed.

Let me know if you do it and how it works.

I looked and saw other people doing this with saltwater. Does it work in freshwater?
SOB fish + a mirror or few self portraits = model citizen?

I have heard it works for flowerhorns and blood parrots. I have never tried it though. Also used for Asian Arowanas, I know that.

Sounds like the mirror trick (where one uses a mirror in or next to the tank to trick the fish.) Fish do not do well when another "fish", that is their mirror image of a fish, is in their territory. The neurological effects of this has been studied:

fish, especially aggressive fish appear, to think the mirror image is another fish. Because the real fish (in the tank) performs behaviors which it intends to intimidate (or submit) to the other fish and it gets none of the expected responses, it creates both aggression and fear.

I think people would say that many fish evolved using aggression and retreat as a mechanism to establish territories for breeding and eating... essential survival practices. People have deduced and written about this for centuries.

If the picture works, (in the way the mirror works), one might surmise It "works" in the same way one could say lobotomies "worked" on patients. In other words it achieves what the owner wants despite the negative affects on the fish.

+1 This practice causes unnecessary stress and fear for the fish.

I agree with this, but the idea is not to leave the mirror or picture in place permanently, but just long enough to get them to accept a new tankmate. It sounds like it would work.
