I've got a problem with one of my clown loaches and I have no idea what is wrong.
For the last week almost i've noticed that one of the loaches has been constantly breathing rapidly with its mouth open.
He/She is also behaving strangly. All my loaches are usually hide inside a big hollow rock during the day but this one no longer seems to care for hiding and just sits outside the tank now. And before they usually dive for cover when they see activity outside the tank but this one again doesnt really seem phased at all. Other than that though he seems fine. Swims normally and physically looks fine (pic attached).
Also i dont know if this is of any relevance, but he does appear to be the smallest of the 6 but only slightly and his stripes are alot darker than his tank mates.

2.5ft 40 gallon which has been setup for about 5 weeks now.
