Had a chat with Andy about these the other night but just wondering if anyone else has any experience with them? Only species we currently have pics for is P. fasciata (thanks TDO) which looks like this:

Hi Andy do you think these could hold their own with more aggressive botiids like Syncrossus?

I,ve got three small Syncrossus in the tank with them ,S.berdmorei ! and I never see any real interaction , the tank is 8ft long by 23inch wide so there is plenty of room, there are also Botias Dario ,Almorei and Rostrata so I guess there must be some contact possibly at feeding time ?

I suspect the L.fasciatus are too quick ,due to their slim build ?

Perhaps in a 4ft tank there might be lots more contact ,hence possible squabbling ?

Thanks for the info Andy. /thumbs_up.gif" style="vertical-align:middle" emoid=":thumbsup:" border="0" alt="thumbs_up.gif" /> Having done some digging I think your fish might actually be P. lijiangensis though. It comes from the same area of China as Sinibotia robusta and according to the description has 10 - 13 dark bars on the body (I count 11 on your fish) plus 3-4 bands on the caudal fin.

Haven't found a lot on P. fasciata but according to Naseka & Bogutskaya (2004) it has 12-14 thin, regular dark stripes on the body which are noticeably narrower than the pale spaces between. It was also described from the Yangtze River rather than the Pearl (but has since been recorded from the latter).

CAFS image of P. fasciata appears to match Naseka & Bogutskaya's description and doesn't really resemble your fish:

What do you think?

Hi

The fish in the photo was only small at that point, probably 7cm TL. The drawing and photos I have of P. lijangensis (Freshwater Fishes of Guangxi (2nd edition), and Coloured Illustrations of Freshwater Fishes of China Vol 1) seems to have a much shorter head/snout than this fish and P. fasciata, and the body bands on lijangensis seem wider and don't appear to narrow near the ventral region (they also break up a little inbetween the bands near the ventral region (like robusta)). I think it is just a young fasciata but would like to see it now it is adult. Looking at the photo and drawing of lijangensis, this fish is not lijangensis IMO.

It seems to match the image of an adult P. fasciata pictured in Freshwater Fishes of Guangxi (2nd edition). Because it came in with S. robusta, doesn't mean it was caught with that species but I can see why you doubt it, though the Yangtze spans a massive region of China.

Cheers Andy, do your fish show any dark head markings?

Meanwhile, this fish appears to match the CAFS one?

I think we are looking at juvenile v adult colouration, or there may be some different populations or even unrecognised sp differences? Hard to say for definite really.

Ive been having a rumage around this morning and I think the fish in the photo that TDO put up could possibly be either Parabotia banarescui or More likely Parabotia lijiangensis, I have one photo of the P. lijiangensis and it matches aprt from the head shape but the fish is clearly frshly dead and from the marks it looks like it was hit in the head /angry.gif" style="vertical-align:middle" emoid=":angry:" border="0" alt="angry.gif" />

Yes Matt, I noticed that Steve did mention the head shape, and for me that was something that stood out but that fish in the photo in "Freshwater fishes of China" has for me definately something wrong about its head.

Hmm its one of those tricky ones isnt it, I want to include it in the book as it has made it into the country all be it as a contaminent I am just not 100% about whether to label it as faciata or just Parabotia Sp or even Parabotia cf fasciata for now /wacko.gif" style="vertical-align:middle" emoid=":wacko:" border="0" alt="wacko.gif" />

The drawings I have of lijangensis also have the strange head shape. I think the lijangensis in the CIFFC book is as it should be.

As I said, the pic in Freshwater Fishes of Guangxi (2nd edition) captioned as fasciata does match the specimen in my photo (albeit an adult and with more faded greener markings, but still has thick body bands, unlike the photo in CIFFC and in Stan's photo).

banarescui and fasciata are similar. The only differences I can find is that in fasciata the dorsal has iii9-10 in banarescui iv9
these are guesses on Chinese translations for fins: fasciata ventral i7, banarescui i6

I cant count the ventral fin rays on the fish in my photo but it appears to have iii10, so this would make it fasciata, albeit this I cannot guarantee of course.

I just got a photo from Stan Sung that shows a sub-adult I suppose for want of a better term, the body colouration is chnaging and the bands are slightly faded and becoming thinner and the body is clearly getting a bit deeper.

He's not so sure anymore Mark - the two dark markings on the caudal fin base are a diagnostic character for P. bimaculata. Just waiting to hear back on locality details but that species was described from Sichuan where this specimen was collected.
