If you ever see these, try them. They stay small, like soft and acidic water, and look fantastic. Be prepared to shell out a few bucks...

Yes! I stumbled across a pic of that fish a while back that was just stunning.

I'm guessing it was either an amazing specimen or its breeding colors. Or maybe it was Photoshopped...

I would love to try these guys. I liked that they were relatively small for a rainbow fish too.

Well, I guess some of the photos might be altered, but they really can look like that. Young and specimens that aren't acclimated don't look so hot. There are also a good many color varieties, some of which look better than others. Naturally, one of the best ones is found inside a national park.

Ahhhhh this is the species we were talking about at the meeting! I'll have to see how my SE Asian blackwater tank goes and keep these in mind... I still have that 45g (which was going to be the original blackwater tank) that I think would be great to house a school of these guys

Edit: While I'm at it, I have to ask... if one wanted to set up a biotope tank with these (I love biotopes, sue me!) what plants would one look to put in with these guys?

If anyone is interested (like I was) I found a US source. No clue on the reputation of this seller, but they seem to be decent.

I don't think I will ever cease to be amazed by the power of internet searches. Remember what things were like before? Seriously. How did anyone do business?!??!

Here's the definative description for the fish...

After reading the script, the biotope tank for these is high tannin (tea) water and no plants, no snails.

I stole this list from the Bowheads forum for others though.

NO KIDDING!!!! WOW JIM!!!!

This is why I love this group, you get so much information when you ask

Jim - When researching these guys a bit I came across the aussie site that listed plants sampled in an area along with fish, and very few aquatics showed up on those lists. Going by pics I was think a snag type deal with only V. nana or similar, nothing too heavily planted. I seem to really be in love with these blackwater tanks that don't really support a variety of plant life... I guess I won't have those nicely trimmed gardens you guys are so good at

Corey;

Nothing wrong with those minimalist scapes. Of all my tanks, Marlene's favourite scape is my shellie tank. A pile of rounded river rocks at one end of the tank with a single Val at the base, and the rest of the tank just aragonite/rift lake sand and escargot shells arranged by the fish. Unfortunately it is in the unfinished basement where you can't really enjoy it. I think if Marlene had her way, they would move into bigger digs and replace the 110 gallon jungle in the kitchen.

You're snag scape would work and would really accentuate the fish.

Also, from reading the 1930 Amandus Rudel discription, I think you could pretty easily reproduce the Stradbroke Island biotope by just having some sand suubstrate (probably silica sand) and running peat moss in a canister filter until the colour gets to the darkness you desire.

Here's a wiki article which would help to understand the environment and history of the area.
