Polka-dot Loaches are relatively undemanding fish and once acclimatized can thrive in a wide range of water parameters, although softer and more acidic water is generally preferred. A very social fish, it is best to keep them in groups of three or more. Numerous shelters should be provided which gives them greater security and generally makes them bolder. Like most bottom-dwellers the substrate should consist of a fine-grained or round-edged gravel
Polkadot loaches can be boisterous fish that like the company of their own kind. They love to gather together in certain shelters and can often be seen interacting with each other. They are an active loach and can be seen hovering around the upper levels. In common with other scaleless or small-scaled fish, they are susceptible to ich and other skin parasites. When treating, be sure to check the directions on your choice of cure and follow the directions for scaleless fish.
This species is very variable in pattern and can change quite dramatically as it grows. Generally, the dark areas gradually increase in size as the fish matures. Some races start off with much more dark colouring than others, and some feature almost sky blue spots within the dark areas. The pictures here and in the photo-search facility show that variability.
