Worried About A Clown Loach

[Amunet]

I'm extremely worried about a clown loach that we have.
It's 1 of the last 2 that we put in to the tank. The other loach has already grown a considerable amount and looks great, but the other one is still very tiny. Doesn't look like it's grown at all.
I'm afraid to take it out of the tank b/c I don't want to stress it out and get it more sick (if it even is), but I don't want to just sit back and do nothing either.
What could be wrong with it?
It was swimming around, but seems to be hiding/resting a lot more. I didn't think anything of this at first since the other loaches hide out for a few days as well, but combined w/ the lack of growth, it has me worried.
I'm afraid that it might have an internal parasite. But how would I even go about treating that if I did take it out of the tank? I know it probably wouldn't eat any meds that I tryed giving it. Probably wouldn't eat anything at all.
Are there meds that will dissolve in the water that will treat internal parasites as well?


EDIT: Well nm.. not that anyone replied anyone lol
Just found it dead. Gonna be paying special attention to make sure none of the other fish have gotten sick.

That's a shame, there are a few different wormers out there. I use Kusuri but I think you can get many in the U.S.

How many loach do you have left?

Have 6 left. I'm a bit worried about a couple of them now b/c they're not as plump as the others.

Haven't tried this med personally but it may work;
