tiny brackish top feeders?

Celebes rainbows are brackish, I believe. What about Werneri (sp)?
 
Yes, rainbows like bosemani are freshwater and ideally should be kept that way, but they won't suffer any damage when kept in brackish as long as you keep the rest of the water parameters ideal, in the same sense as mollies and brackish BBGs in freshwater.

That's not what Heiko Bleher says. I don't know where you're getting your information from, but it's hard to imagine any source better than Bleher when it comes to rainbowfish. I think that it's important to debunk the myth that rainbowfish species like bosemanis and praecox can be considered brackish when they are not.
I. werneri are also a freshwater species that shouldn't be kept in a brackish tank: "best results will be achieved if maintained at a temperature range of 23-28°C; pH 6.0-7.0; and water hardness of 10-70 ppm (mg/L)." (from Adrian Tappan's Home of the Rainbowfish: http://members.optushome.com.au/chelmon/Werneri.htm ).
As for the celebes rainbowfish, I think they are freshwater, but I can't be sure because I'm not too familiar with the Telmatherina genus
 
Yeah, I wasn't sure about the Werneri. Pretty sure about the Celebes though. Bosmani is mute, as they grow quite large & it's only a 10g.
 
I wouldn't trust anyone religiously. I don't think anyone considers those rainbows brackish, just as no one would consider a black molly to be freshwater. But they can be kept in brackish and still thrive.
 
You mean brackish invertebrates? There are quite a few, though you're unlikely to see them in the hobby.
 
Nerite snails do quite well in BW. Also ghost shrimp.
 
well, just back from a local chain store, and they had a lot to keep me thinking... they had a ton of glass fish, in various sizes, some celebes rainbows, although no one could point them out to me... lol, and a lot of crabs as well.. It took everything I had not to buy them on the spot, but I'm not quite ready, so I held off. Instead, got 1 tiny hatchet for my 20gallon... been looking for them for so long.

Seriously,
Bleher has introduced hundreds of species into the aquarium hobby from locations around the globe, many of which he discovered himself. He probably has a dozen species named after him and has spent his life studying, discovering and acclimating species to aquariums, and rainbows are one of his "specialties". Yet still you dismiss his opinion as if it was the opinion of just another hobbyist, when in reality, it is the opinion of an expert in the field. And for the record, it also happens to be the opinion of several other rainbowfish experts. And by experts, I mean people who have kept and bred DOZENS of species of rainbowfish each. So why should we take your word when your main argument has to do with black mollies? Tell me, what is your source that is so infallible that it should be believed over the word of Heiko Bleher and other rainbowfish experts?
