can u clear up witch is banned and why?Very fine gravel is best, I'd class them as temperate rather than cold water, the ones we get over here are the Chinese weather loach which requires higher temps than the Russian weather loach which is a banned species in the UK.
What size tank do you have? I ask as they can get to about 12" long so need something more than that width.![]()
The european/russian species is Misgurnus fossilis and the chinese species is Misgurnus anguillicaudatus. Fossilis is banned as it is able to survive over here in water of 5C (winter), anguillicaudatus "apparently" cannot.
