Update: Apistos Cockatoos
I know several people were interested in how it would go when I introduced 5 male Apistos Cockatoos into my community tank. I'm happy to report that there have been no problems whatsoever. I also have 3 Bolivian Rams along with the typical community stock of neons, rasboras, YoYos, and a few misc. fish like an ember, endler, etc..
I'm really happy with the Cockatoos that I bought from a guy on Ebay. They were juveniles when I got them and they're all growing well with lots of color.
So, other than a brief chase here and there, and a little posturing between the rams, all is well.
Have a great weekend.
