Has anyone here kept A. botia? We had them in at the shop on a few occasions and they never seemed particularly aggressive to me but I see conflicting info about their behaviour online. Also, other than a larger adult size, how do you tell it apart from A. urophthalmus?

They're not very aggressive. About 6 adult specimens will happily coexist in a 20 long. Their habitat is mostly open sand and leaf litter. One disadvantage is they don't do too well when housed with similarly sized Schistura in small tanks. They invariably get beaten up.

As to differentiating from urophthalmus, just look at the shipping manifest /tongue.gif" style="vertical-align:middle" emoid=":p" border="0" alt="tongue.gif" />

I think the stripes on the uros run almost all the way down to the ventral surface.

Thanks Rahul. /thumbs_up.gif" style="vertical-align:middle" emoid=":thumbsup:" border="0" alt="thumbs_up.gif" /> Can you find botia around your parts or are they restricted to northern India?

The species we get around here is A. sinuata (see pic, ignore genus). A. moreh in most of the literature. The latter species is from around Pune.

A. botia is restricted to the ganges basin, afaik.

It is a pretty wee thing. Are those two not officially in Acanthocobitis then?

Yeah, they've very pretty. But complete wimps. Even the smallest schistura will knock them around.

Not very wee, Matt, the fish in the pic is about 2". Biggest I've seen was a shade over 3". Some of the publications list A. moreh as valid, with A. sinuata as a junior synonym. Most list both as a synonym of A. botia. The fish from South India is a distinct species, at least.

Long story short:

Fish from Ganges/Brahmaputra drainage = A. botia. Everyone agrees on this.

Fish from Krishna drainage/central India = A. moreh. Some agree, some do not. I have not seen specimens, so am on the fence.

Fish from Southern India = Obviously distinct from A. botia. Most Indian authors consider it to be the same as A. moreh. Day considered it to be a distinct species, which he named Noemacheilus sinuatus (all 3 were in Noemacheilus at that point). Until I see a specimen of A. moreh from the correct geographic region, I'm going to agree with Day, and consider the south Indian fish a distinct species.

I really should rename the pic to Acanthocobitis, but I is lazy.

Now I am sated - the reason I initially asked is that it seemed weird that A. botia and A. urophthalmus are so widely separated geographically with no species inbetween. Thanks a lot Rahul. Yes you should organise the legend on the pic then allow us to use it in a profile... /biggrin.gif" style="vertical-align:middle" emoid=":D" border="0" alt="biggrin.gif" /> /tongue.gif" style="vertical-align:middle" emoid=":p" border="0" alt="tongue.gif" />

This is what I have for urophthalmus - what do you guys think?

No takers on the fish above?

Here we have A. pavonacea - The Dark One wrote an interesting paper regarding its taxonomical position a couple of years ago. I have that and have added some information into the notes but does anyone know what kind of habitat it prefers? It was featured in 'Inland fishes of India and adjacent countries' by Talwar and Jhingran so maybe there's some info in there?

Hi Matt and retro.

In 2008 I did an article covering Acanthocobitis for BSSW Report in Germany, discussing the alleged synonyms of A. botia, inc. mooreh and sinuata. Rahul kindly provided the image of sinuata. Do you want me to email you the English text Matt?

The full printed reference is:

Grant, S., 2008.
Schmerlen der Gattung Acanthocobitis Peters, 1861.
BSSW-Report 20 (3), 49-52.

Here's a pic of purported A. moreh by Madhu. I noticed over at IAH that this species is considered valid there so just wondered if anyone has an opinion as to whether we should give it a profile or not. Same goes for A. sinuata as posted by Rahul earlier in th¡s thread...

Well, then all southern caught (i.e south of Krishna) ones would be A sinuata?

Few things which we have noticed (nothing new )-
The largest one caught was 5"+ (caught by Madhu)
They were mainly found in cool streams where we also found one or more species of Schistura sp
Only difference - Schisturas prefer rocky/pebbly places and these prefer sandy bottoms. Could clearly see this difference.
At least at one place, they were seen in a group.

In my 2008 article I have already said that mooreh (not moreh) should be valid IMO, and it is possible that sinuata (not sinuatus if valid in Acanthocobitis) is too (it certainly wont be a synonym of botia IMO, IF it is a synonym of anything then it would be a synonym of mooreh). Whether this pic is mooreh is difficult to say bearing in mind how poorly studied they are. The question to ask is which river/system was the fish caught in?

If from the Krishna system then probably mooreh, if from the Cauvery then probably sinuata (if indeed that is distinct from mooreh) - my 2008 article discusses all these issues, including Nemacheilus aureus Day, 1872.

Yeah was re-reading it earlier which was what inspired me to post. /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> Sorry for the mispelling though - beg you to forgo the mandatory bout of pestilence on my family! The fish pictured was collected from the Mutha River so it's Krishna drainage alright.

Thanks for the info Deepak! Which Schistura sp. is it found with?

We caught/spotted them in streams joining Sharavati and Tunga.

Other loaches caught/spotted at the same location- Schistura semiarmatus, Schistura nagodiensis. Im not sure, think we also caught Schistura denisonii.
Others - Rasboras and danios

@T.D.O, Matt
Could I get the article on Acanthocobitis please

Cheers Deepak. /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

@everyone else - guess the best we can do for now is list the 'possible' A. mooreh as a 'sp.' pending official confirmation?

If from the Krishna then I would say yes, mooreh. I personally think it warrants a profile, not the least because mooreh is deemed valid by Indian authors, just that it is placed in Nemacheilus by them, but is certainly an Acanthocobitis (subgenus Paracanthocobitis) and valid IMO. Kottelat questionally synonymised it with A. botia but he had no specimens to hand.

random2 - I only have a pdf of the German language article but I do have the text in English in a Word document (but none of the accompanying pictures). If you want that, please give me your email address.
