ID for "weather loach"

[AleXander]

All fish in these pictures were sold to me as "weather loach". One of them is actually Misgurnus anguillicaudatus. The others I am not so sure about.

above: on the left is a true weather loach (or so i believe) on the right is this little guy.

I thought the above fish would "grow up" into a weather loach. He has not.
the next fish are not like my original loach either.




I can take better pics if needed

Hi,

The skinny loach seems to be a Misgurnus, too.

The third loach is a nice patterned Lepidocephalichthys guntea

[AleXander]

The Guntea were put in an unheated tank. They were going to go with the other loaches (which is why I only got 2) but since that tank gets colder I put them upstairs where it gets warmer. I was about 65 F / 18 C when I checked it mid morning. Will this be ok or will I have to rehouse them?

About the little guy. I am confused that a fish that is raised for food would grow so slow. I've had the little guy for a couple of years and he has taken on a tad bit in length but no girth.

for some reason the pics keep getting cropped ant the ends so here is a link to the full pic so you can see the tail better

Is this actually a mini Misgurnus?
