One more Danio compatibiliy question -- Hikari ?

Gary Herring · Post by **Gary Herring** » Tue Aug 01, 2006 1:59 pm

Did they have longer fins than the usual variety? If so, it sounds like the varient that I have, known as the 'meteor' minnow. I've had no probs with aggresion though. I would post a pic but coppermine's not co-operating at the moment. It's highly unlikely, by the way, that what you have is a seperate species - there are only two discribed species in the Tanichthys genus - the common WCMM is T. Albonubes, and the other is a smaller (prettier?) fish from Vietnam. Can't remember the species name exactly, macganamae or something.

No, it is not the "long-finned version", I've seen them advertised. I'll post a pic of mine some time later (100F+ heatwave here and light is turned off in small tanks).

To clarify "aggression" : they were not aggressive to each other, I think they were just much more playful. But the way they dived on Gastros and Kuhlis -- like a hawk would -- was serious.

Back to Danios: the place that sells them here actually has a number of other potentially interesting dither options. These are four other particularly attractive ones (no idea right now which ones are suitable for hillstreams so I'm not about to get them, but these are nice):

Chili Rasbora:
Boraras brigittae

Boraras maculatus:

Gold-ring Danio:

Cheetah Danio
Danio nigrofasciatus:

Thanks for all the help.

All right. I have six of these guys being acclimated right now, together with six Glowlights. Seem active, and insane: Hikaris are trying to jump out of the bags (Blues in one, Yellows in another). The only problem so far is that they have fairly weak colors, hopefully this is something that will correct by itself or with a few bloodworms. The fish came from the new place,

http://www.franksaquarium.com

which does mail order and also happens to be within reach from me, so I visited Frank today to pick up the fish. (Yeap, I liked what I saw there, and the guy is clearly serious about doing good job.) If you look through his site, you will see a number of other Danio species offered, as well as some Rasboras. The only problem is that it is not immediately clear which of the other species are suitable for river tanks; this is something I'd like to know for the next time.

In another 20 mins we'll find out if these species mix or kill each other...

Nice selection he's got there. The only one that I know is definatley not R/T suitable is the undescribed 'Burma' species.

BTW, the fish on the top left of the home page is that newly discribed Vietnamese 'white cloud' that I was on about. 8 of them would be a nice addition to a river tank I reckon. Hmmm..... new tank idea..... Vietnamese biotope with them and S Lineolata

Boraras would definitely be a no-no for a R/T. They're soft water swamp type locale fish. Nonn Panitvong had a video of a big shoal on his site taken underwater. It looked like he was swimming in Coke.

No suitable rasboras? -- darn, those chili ones were very nice. I guess they are for a small planted no-current tropical tank.

We can also nix Inlecypris auropurpureus. Unfortunately, there was a mistake made yesterday, so I have one of these guys sneaking with Blue Hikaris...was not immediately clear since the colors took a few hours to develop. Hikaris are playing with the stream, he is hiding from it....and he needs high Ph too, I think.

Colors, btw, came out very nicely, and fish is very active now. The colors are still not as bright as on the photos, so if someone knows how I can try to improve it, please say.

The two other nice ones are the Cheetah and Gold Ring. Any idea about their river-tank compatibility?

I have a school of "cheetahs" (danio nigrofasciatus) in a small tanks with a fair amount of flow. They seem to like it, but do not appear to be as current oriented as kyathit and choprae. By the way, the cheetahs develop a slight purple sheen to their flanks and are even more attractive than the pic illustrates.
Another possibility, if you can find them, would be danio roseus or the "purple passion danio". Martin has them and they are very attractive. I saw them for the first time the other day and was very impressed.

Thanks, Jim,

Cheetahs are very attractive and something to certainly keep in mind for some future project. Which loaches are you keeping them with? (I _think_ they are a bit too large for hillstreams).

Thanks for the Roseus hint. BTW, the most attractive Danio of all, IMHO, is
http://www.danios.info/Contents/species/danio19.asp
I saw these once only and did not react quickly enough....

Jim Powers · Post by **Jim Powers** » Sat Aug 05, 2006 3:22 pm

I have the cheetahs in with a few small schisturas (beavani and savona). They are certainly not too large for hillstreams as they only get about 1.25" or so in length.
By the way, I am floating a bag of roseus as I am writting this. I will add them to my mixed school of kyathit and choprae.
For some reason I can never link to that danio info site on my computer.

Aha. Frank's site said 2.5", so I did not even consider them. Stupid of me not to recheck. Thanks.

Congrats. Problems of linking to Danios.Info have been mentioned before, try using IE instead of Firefox.

I didn't say NO Rasboras mike, there's a lot that might fit the bill, just not Boraras sp. And your guess is right

I would go the Danio route. Danio roseus (AKA Purple Passion Danio)are beautiful, but very dependant on light source to really look their best.

Kyathit are fabulous as far as I'm concerned and as I see you've tried to look at the Danios site, I'll tell you that they're Peter Cottle's favourite species.

Martin.

I have also noticed that there seems to be some very colorful pearl danios around these days. I think they are the "tweediei" version and almost look like roseus.

mikev · Post by **mikev** » Sat Aug 05, 2006 7:10 pm

Thanks, Martin.

Great pictures, as always!
Kyathits are hopefully on their way here, they were ordered a while back.

It occurred to me that there may be a use to Boratas too: dither for Kuhlis

Martin Thoene · Post by **Martin Thoene** » Sat Aug 05, 2006 8:54 pm

Yes, I think Boraras would be great in a kuhli biotope type of setup.

Martin.

Since this thread is still around.... any idea which Danio is this:

?

Sorry, this is the best photo I can make (nearly a hundred attempts), he either hides or moves too fast. As it happens, I have this fellow instead of a Hikari. Identical body shape, and it seems to be less happy about the current than the Hikaris (thus some hiding under leaves).
