Most of the loaches are not very large, being only a few inches, but there are exceptions with a few of the Botia reaching over 12" (30 cm) and the exceptionally large Royal Clown Loach which can reach up to 20" (50 cm). The body forms, though most often elongated and rather cylindrical (and a few that are flattened), are quite varied. They can be chunky and heavy, worm-like, or even eel-like.For the most part these fish are bottom dwellers, but many species have a unique intestine that can act as a respiratory organ similar to that of the Corydoras. This allows them to absorb oxygen at the surface directly from the atmosphere, a feature that helps ensure survival even if water conditions are polluted or are oxygen depleted.Some Cobitidae species were believed to be extremely sensitive to atmospheric pressure so that when the weather changed they would get quite active, swimming up and down in the aquarium. These fish have been used as living barometers and are referred to as 'weather fish'. A noted example is the Dojo Loach,Japanese Weather Fish, or Weather Loach. It is uncertain however, whether these nervous displays are from a barometric change, some other change in conditions, or just their unique behavior.
The clown loach, Botia macracanthus, is a quirky fun fish for the freshwater aquarium.

Thanks for you reply. I am very happy with the small clown loaches. I hope they don’t get too big for the 15 gallons aquarium.. I’ve already noticed a smaller snail population. Clown loaches are great additions to community aquariums and get along with all kinds of fish.

After changing my aquarium size from 29 to 55 gallons, I introduced a Yo-Yo Loach into my tank. He was quick to adapt to his new surroundings. He is now almost 3 inches long and is a fish to watch. His demeanor is quiet, but very active. I recommend this fish to all who like bottom feeders.Kuhli loaches are my favorite aquarium fish because they are so interesting fish to watch. They look more like snakes than fish, and you will often find themhanging from plants and other objects in the tank. Clown loaches are peaceful fish and can be kept in a community tank. They usually swim alongthe bottom of the aquarium, similar to corydoras catfishes. Because of their nocturnal habits, you should feed them at night. Don't turn on the aquarium lights -just put a little food in for the kuhli loaches to eat at night, although you will oftensee them eating during the daytime as well.Their mouth has barbels and faces downward, which means they feed from the bottom of the aquarium. Kuhli loaches reach an adult size of between 3-4 inches (7.5-10 cm) in length. Kuhli loaches belong to the family Cobitidae.The Dojo Loach is a fairly popular fish in the aquarium trade usually costing anywhere from $8 - $15 US Dollars. The Dojo Loach is sometimes called the Weather Loach because of its reported behavior when the barometric pressure drops. Some hobbyists have reported witnessing increased activity levels, erratic swimming, etc. when storms are approaching. The Dojo Loach is originally from North Eastern Asia and China but have been imported and introduced into other habitats in various places around the world not always with good results. This Loach is considered a food source in some Asian countries.
