When CL's are jousting or feeling dominant, they turn gray. This color shift can be instant, or last for days. I dont know about all this Northern & Southern variety stuff, but if there is 2 species, this is not the way to identify the difference.
Those are regional variants, not separate species. There is another somewhat similar "clown loach" species, but it is very rare and obviously different from regular clowns.JakeH;3777789; said:When CL's are jousting or feeling dominant, they turn gray.

mamapuff;3778632; said:most of my loaches are grey in color. They were all dark when I got them, but have changed over the last year. The larger ones were acquired after the original 15. I do have ones that have just the red pectoral fins and the ones that have the black spotch on them. Other than those two differences, I just see the ones that don't sleep in the wood as much, getting much more food. Sometimes I take the decor out for a week or two and let them all shoal together and get food together. Once the wood goes back in, I tend to find them inside sleeping and its like they never move.
justin guest;3777308; said:I find the going gray problem is related to water quality and diet. Some of my best coloured cl´s were over 20cm. As to power feeding use predominantly mussel meat as a fresh food source and a good high protein/fat pellet (fish shop brands usually aren´t good enough as opposed to aquaculture feed) and keep oxygen high and do min. weekly water changes. Growth rates can vary as mentioned above.

Are your hiding loaches of a different size to the rest?mamapuff;3778632; said:most of my loaches are grey in color. They were all dark when I got them, but have changed over the last year.
