Xenotilapia rotundiventralis

Postby Multi » Sat Apr 21, 2012 1:01 pm

Hello!

Finally I got my Xenotilapia rotundiventralis. I found them in a place in Germany in January this year, and finally they arrived at my house at April 17 2012. There is so little information about this species on the internet, so I would hear if there is anyone others there have them? It is a very nice species. :)
They all survived the shipment from Germany to Denmark, so now I have 20 of them swimming around in my 360 liters aquarium in the basement. They are so fine.

When they arrived, they had some dark markings all around the body, but they don’t have it any more. Sometimes a little bit at night, but otherwise they are silver with these beautiful blue and shiny dots or stripes, down along the side of the body. They were pretty shy when they arrived, but they quickly lost some of their skittish behavior, and I am surprised how little shy they are now. 19 of them are swimming around near the front of the aquarium, a little bit above the sand bottom, and sometimes one of them swims down to take mouthful of sand, but they are not sandshifting alot. They all swim together, but a single fish have chosen to be under a large rock in the aquarium. If I take a finger to the glass, in front of where the fish is, it raises all the fins, and tries to chase me away. :) Why do you think that it does that? It doesn’t look sick, but I also think that it can’t already have found a territory that it protects so strongly?

I think that they feel more and more like “homeâ€Â

Its become rather famous.
http://ecol.zool.kyoto-u.ac.jp/~tetsumi ... html#X_rot
and interestingly has invisible pair bonds
http://rsbl.royalsocietypublishing.org/ ... .1006.full

The study was the first to detect pair bonds in animals in which physical proximity has not been observed.

Looking forward to reading (and hoping for some photos) of how they do in aquaria for you.

All the best James

No, Creepy85. The correct name of this species is Xenotilapia rotundiventralis. Earlier it was named Microdontochromis rotundiventralis, but in 2003 it was removed to the Xenotilapia genus, and is now named X. rotundiventralis. Many still often call this species for Microdontochromis rotundiventralis (including me), but the correct name is Xenotilapia rotundiventralis. ;)

I have another thread about my tank on a danish site, where I also have uploaded some pictures of the fish. I can post some links, so you can see them, until I find out how to upload pictures on this site. :)

First a picture of the aquarium : http://cichlids.akvariefisk.dk/storage/ ... DAFA3F.JPG

Then one of the fish school : http://cichlids.akvariefisk.dk/storage/ ... 8A5124.JPG

There's a space in the URL that you need to remove.

The species was first described in 1997 by Takahashi, Yanagisawa and Nakaya.

Later, in a revision of the genus Xenotilapia, (BY THE SAME GUY WHO DISCOVERED IT IN THE FIRST PLACE) Takahashi, T. 2003: Systematics of Tanganyikan cichlid fishes (Teleostei: Perciformes). Ichthyological Research It was described as Xenotilapia Rotundiventralis.
