thinking about it more, they may not be popular in the hobby, but there MUST be smaller brackish fish, the size of neons and smaller... the food chain doesn't usually just skip sizes... or is this where guppies fill the void?
In other words, you don't have anything to back up your position. The point is, I hope you stop suggesting rainbows as brackish fish, it's a myth that shouldn't be perpetuated.
seriously xman, get your own thread for that soap box of yours. no one cares how expert you think you are. you're just making it less likely anyone will discuss the topic at hand, my stocking plan. really. grow up
They show up on aquabid from time to time. I also know a couple of people that keep these from the bowheads forum: http://bowheads.org/forums/index.php?gclid=CMyluf6vm4gCFR8eYQod1W75XA
You could post there to ask if anyone has some available, or if Gary Lange is giving a talk in your area, he might bring some cyanodorsalis eggs with him. Cyanodorsalis are related to threadfins which would account for some of the similarities, but their coloration is different and threadfins have much longer fins.
And you need to live up to your handle a little better. My posts aren't killing your thread, and I've supplied you with some links that are directly related to what you're asking for. You also specifically challenged me to back up what I said and I did, so don't jump all over me when I then challenge the other guy to back up his claims.
I don't care for this because it's too high-school and pointless for me. If you read through the pages, you're obviously just looking for an argument, and whatever result comes out of this isn't going to be of use to anyone.
You want me to stop suggesting rainbowfish for brackish tanks? That'd be quite easy, because this is the probably the first time I've done so. Did you think this comes up often?
You're right, I'm wrong, no rainbows in brackish everyone. If that's what you want to hear and what will stop this, there be it.
