Hi there :-)

On Wednesday I got (after three long weeks waiting....) finally my Rhinogobius mekongianus. They are still very young and almost 3,5 cm long. And unfortunatly very skinny. But they are also very curious and trustful.

I got 10 fishes, unfortunatly more males than females. But as I can see, there are 2 females at least.

Now they must grow up and I hope, then I will see, how they will spwan :-)

Great! /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> Please keep us updated on progress Jutta. Any idea which part of the Mekong they originated from?

Yet Jim, I think that they do not look so healthy.

Matt, as I understand it, they were caught in Burma.

Of course I will keep you updatet :-)

Very nice fish ! at first glance I'm reminded of a fish that Torso/Charles keeps which I think is called Rhinogobius Rubromaculatus ,its the accentuated spots which I think are red in Rubromaculatus ,whereas they appear black on your fish ?

I'm not overly familiar with the gobies in general but years ago possibly the 80s I kept a fish called Vaimosa which were I think exported from Thailand ,they were one of those fishes that weren't common but would appear every so often ? oddly since Gobies have become more available to hobbyists I've never seen them since ! having said that they weren't the most colourful /rolleyes.gif" style="vertical-align:middle" emoid=":rolleyes:" border="0" alt="rolleyes.gif" /> if my memory is right they were greyish in appearance with the lower jaw being white , I once added a bag of Rasbora Uropthalmus and watched as the gobies swollowed the lot /wacko.gif" style="vertical-align:middle" emoid=":wacko:" border="0" alt="wacko.gif" /> I had quite looked forward to keeping the Rasboras /blush.gif" style="vertical-align:middle" emoid=":blush:" border="0" alt="blush.gif" /> lessons learned in the joys of fishkeeping /huh.gif" style="vertical-align:middle" emoid=":huh:" border="0" alt="huh.gif" />

Are those Vaimosa now Rhinogobius ?

Seems that Vaimosa is now synonymous with either Pseudogobiopsis or Mugilogobius depending on species Andy?

Those red-spotted fish Charles had are R. rubromaculatus and chuffed to say they've been residing with me for the last month or so after he very kindly sent them over with some visitors. Must take some photos. /rolleyes.gif" style="vertical-align:middle" emoid=":rolleyes:" border="0" alt="rolleyes.gif" />

Can ab pls send me the OD of R. mekongianus? I would like to double check the identify with fishes I caught in the Red River in Guangxi, China PR. My fishes are much more colorful then those in Europe - with plenty of red sparkles all over the flanks. I believe that all European stock originated from an import done by AquaGlobal/Berlin. The fishes have been IDed by Ingo Seidel, a catfish specialist.

The OD is:

Pellegrin, J. & P.-W. Fang 1940: Poissons du Laos recueillis par Mm. Delacour, Greenway, Ed. Blanc. Description d'un genre, de cinq espèces et d'une variété. Bulletin de la Société Zoologique de France v. 65: 111-123

I am also interested in:

Smith, H. M. 1945: The fresh-water fishes of Siam, or Thailand. Bulletin of the United States National Museum No. 188: i-xi + 1-622, Pls. 1-9. (a very comprehensive work).

Thanks for any help.

I would also like a copy of the first paper if possible - been looking for a while.

The Smith book is available here.

Unfortunately I only have a paper in which the R. mekongianus are mentioned only in passing.

But there is news: there is a first, large clutch. Already well developed, but I have taken it from the dad before the little ones hatch in the parent pool.

That I know, Jim! I did the day before yesterday in the duospilus-tank found a stone deep down in the sand. I still have seven larvae rescued, the rest was unfortunately already hatched. And now I do not know who is the dad ... I have to wait until these little show color. And in my R. cf. lungwoensis tank I'm missing a male. Where he has dug itself, I have not found out too :-)

I didn't see my male for  15 days so I finally went digging. He was under the last of many rocks! I siphoned the tank while digging and found 3 larvae in the bucket. He's gone again. I think I'll just leave him alone this time.

Here they are now. 17 days until hatching.... what a long time! The yolk sack is almost disappeared and they eat from the first minute.

They are so cute....
