Pareuchiloglanis macrotrema

[Yanger]

I have kept this fish for about 3 months, and I took these photographs during a water change. Usually he never emerges from hiding during the day and I had to isolate him in a box to take some pics
Pareuchiloglanis macrotrema, a wc specimen from Yun Nan province in China. This is quite a rare but hardy cat and can stand temps from 15 degrees C. to 25. Mainly eats live worms.

Incredible!!! Is it possible to to post larger images please, I am able to see only thumbnails. What sort of tank have you kept this in and what was the habitat like?

Tremendous

I have no idea how to post bigger pictures, sorry man. It's the first time I've used this website so I'm kinda unfamiliar with posting pics here. This fish lives in fast flowing streams and stick to rocks, I think they are nocturnal. They mainly feed on live prey. My tank has only got three rocks in it and no substrate, and there are only two other fish in their with this catfish, two small stream fish to help clean up after meals. The water current in this tank is extremely strong, as the catfish can only stay healthy if he stays in a strong current all the time.

why are the attached pictures so small, hhh

This fish could also be a Pareuchiloglanis cf. longicauda, since the two species coexist in the same region, and that there are so few pictures available for them.
here are some larger pictures.

I have uploaded bigger and clear pictures of this Pareuchiloglanis macrotrema or possibly Pareuchiloglanis cf. longicauda.

This photo was taken the day I received him. He had quite a rough trip of over 3 days, shipping all the way from Yun Nan to Beijing. His skin was scarred but fortunately, he's in perfect health and his skin has recovered from the scars.
The second picture was taken a few days ago, and you can see that he's skin has perfectly recovered from the scars.

Awesome!!! What was the water temperature where you collected this and what are the tank mates presently? Its good to note it is taking food, these sisorids are sometimes downright stubborn and just wither away.


Edit:Has the ID been confirmed?

The temperature was around 18 Celcius. It is housed with a native carp species (Barbodes caldwelli)and a topmouth white fish baby. It had no trouble eating the day it got here, and it seems to have a natural swallowing reaction when worms and shrimps approach its mouth.
Thanks for supporting. It has about 95 percent chance to be a Pareuchiloglanis macrotrema.
here are some of its tank mates, a Barbodes caldwelli baby and a topmouth white fish.

Very nice set up you have going there! I too was obsessed with keeping reophilic catfish until recently.

Is it possible to get a few more closeups of the mouth?

@Silurus described a Pareuchiloglanis in 2004, I don't think I've got the paper - but perhaps he could comment on the ID. I agree it's a great looking fish.

What water temperature are you keeping it at @Yanger?


Cheers,

about 21 Celcius. My biggest guess is Macrotrema, however, the species isn't documented on this website.

I am traveling at this moment and my roommate is taking care of the fish. I'll get a few close ups once I come back.

There are six river drainages in Yunnan that Pareuchiloglanis is known to occur: Irrawaddy, Mekong, Pearl, Red, Salween and Yangtze. Without knowing exactly which river system the fish came from, it would be almost impossible to identify based on photographs alone.

This fish was collected in the Pearl river drainage in XiShaungBanNa. I've just found some data of this fish on a Chinese website, and the Chinese name for him is 大孔鮡，and there are quite a few pictures of this species. It is quite well spread in Yun Nan, and inhabits streams around the Pearl and Red drainages.

If it was collected in Xishuangbanna, it would have to come from the Lancanjiang (upper Mekong River) drainage. Then it is not P. macrotrema, which is known from the Yuanjiang (upper Red River) drainage. Pareuchiloglanis gracilicaudata seems more likely.

That is highly possible. The only existent pictures of Pareuchiloglanis gracilicaudata are pictures of preserved bodies, without much coloration left, so I don't think we can say for sure what it is yet. Highly possible, though.

[Jools]

If you could get some slightly better pictures, I would like to add them to site for that (Pareuchiloglanis gracilicaudata) species.
