Clown Loach - in The Aquarium

In The Aquarium

A harmless, very active and sociable fish, clown loaches are best kept in groups of 5-6 or more. Due to their potentially large size, a 75 to 120 gallon (283 to 454 litre) aquarium should be the minimum size used.

These fish have bifurcated subocular (located under the eyes) spines, which are used as a defense mechanism and for obtaining prey. If a loach deploys its spines while caught in a net, untangling it is difficult and can result in injury to the handler or the fish. Aquarists recommend that large specimens are double or triple bagged, or placed in a solid container when being moved.

When kept in groups smaller than 5, clown loaches may spend lots of time hiding under obstacles in the water. Tiger barbs and Panda corydoras associate happily with clown loaches, and the three fish may school together.

Clown loaches make clicking noises when they are excited or during feeding. This sound is produced by the grinding of their pharyngeal teeth. Sometimes clown loaches swim on their sides, or upside down, and appear ill, or lie on their sides on the bottom of the tank and appear to be dead. This is normal behaviour so the aquarist should be aware of it to avoid removing healthy fish from the aquarium.

If clown loaches do not come out of hiding, there are some easy things to adjust so that the clown loaches will be more comfortable. A good tank setup for a clown loach should include ample shade, real plants, hiding places and other peaceful fishes. Make sure the environment is not too bright initially. Provide shade from tank lighting. The tank should not be next to a window unless ample shade is provided. Window tanks with ample sun will allow Chromobotia to warm themselves and do their dominant color dances with more splendor as they flash in and out of sunlight slicing through openings in natural cover. An example tank will have a powerhead to create a current for them to swim against as well as cover to stay under while doing so as in a mountain brook of clear water with current rushing down between boulders. In fact, clowns show a strong preference for larger rocks taken directly from mountain streams too swift to allow algae growth. They will peck at these rocks often and always sleep under and on them.

Clown loaches are keen observers of other fish in the aquarium; they observe and react accordingly. If other fish are skittish and hide, clowns will observe this and do the same. Make sure that other fish in your community tank are docile and not prone to hide. Chromobatia will all sleep together under anything they can fit under in your aquarium.

Because clown loaches come from rivers and streams, they are accustomed to having other fishes and plants in their environment. Not having plants and/or other fishes can cause clown loaches to become stressed and to go into hiding. Especially on introduction to a new tank, it is important that lots of placid, active smaller fish are present. Until you know what fish company they like best, use many colors and varieties of inexpensive minnows. Another important thing to remember is that since they do come from a fast moving river environment, they need a tank with lots of clear, well filtered and fast moving water which can be achieved with proper filtration and the use of powerheads. Stream rocks should allow resting back eddies as well as shade and cover.

Before introducing clown loaches to your tank, make sure the fish you currently have are compatible because aggressive fish will stress your clown loaches and may need to be removed. Clown loaches are particularly susceptible to Ichthyophthirius (ich),or white spot disease, so they must be watched closely when initially introducing them to a tank and when new fish are added. Due to having little or no scales at all, a reduced dosage may be required when using certain types of medication, possibly reducing the effectiveness.

A variety of food should be provided for clown loaches, and their behaviour should be observed during feeding. In a community tank other fish may take the food before it reaches the bottom, where the clown loaches normally feed. However. with a tank supported with natural environments, Clowns are very noisy surface feeders who will assert themselves to take the most and the best of bloodworm. Most clown loaches accept commercial flake food and sinking pellets as their dietary staple, but thrive with a variety of food: live (worms, brine shrimp, small snails),banana, plant matter, freeze-dried (tubifex worms, especially if it is fortified) and frozen brine shrimp (always thaw frozen food to aquarium temperature).
