Yeah a ton of people do a bunch of stupid things all the time that doesn't make it the best thing in the world now does it? I have had balas, silver dollars, tin foil barbs, clown loaches, and rainbows in with my rays. Everything eventually picked on them especially once they start breeding and they beat each other up a tad then they just pick at all the areas on the rays that are already picked at and it goes bad pretty fast. If you notice most (not all) of the ray keepers that are breeding rays have ray only tanks....there may just be a reason for this. And I believe it says in one of the stickies the best tank mates for rays.....is more rays

I will never say I know it all but i know a fair bit when it comes to rays. I got my first retic in 2004 and now I have one of the only mature retics anybody has ever seen top that off with as far as I know I have the only breeding retics anywhere what I am doing must be working. Never said it's the only way but after trial and error and time I can tell you I have a ray only tank not because I wanted it to be that way but because thats what worked.
