Cobitis loaches

Post by lof » Fri Jan 11, 2019 9:13 pm

I recently got some Cobitis loaches. Has anyone kept them?
I know Rachel O'leary has them in her 'hillstream' tank, but I have no clue why because they are not tropical/subtropical, and don't come from flowing streams at all. They are said to require cold winters if they are to live beyond a couple of years of age. Is that correct?
Do they burrow? I've yet to see them do that.

I don't have any experience with them.

The only Cobitidae I have experience with is Acantocobitis, which is far different.

Cobitis are found in the tropics, but also in Europe, in fact 1 species is found here in NL waters. But it is unlawfull keeping this species here, they are protected.


As far as I know, all Cobitidae comoe from clean water, and I thought all from streaming water. If they are a northern species, you will have to provide them with cold water, which is not easy.


4-5 C in winter, and in summer max 20 - 25 C. And lots of water changes

So I have read quite a bit on Cobitis loaches (scientific... not practical... there is very little about that) and there are no tropical species. All of them occur in Europe or Northern Asia. Maybe this idea of them coming from 'streaming waters' is because Rachel O'leary says it but their primary biotope is always stated as muddy and still waters, though they have sometimes been found in slow flowing waters as well. And the reason for that is because C taenia is one of the most widespread f/w fish there is, so it's quite silly to have it under protected status...

Some temperate fish need cold winters, for others it makes no difference, I don't know about Cobitis loaches.
