FAQs

Q. Can clown loaches be handled frequently?

The clown loach has a movable spine present below the eyes that can be extended to inflict a painful sting (though non-venomous). Hence, you might want to be careful while handling it every now and then.

Q. Are there any signs to look for to know if your clown loach is sick?

If your clown loach is infected by ich, it might show up certain symptoms like white spots on the body. In case of another parasitic condition, commonly referred to as ‘skinny disease’, your fish will begin losing weight (leaving them ‘skinny’), no matter how much they eat.

Q. Is it normal for a clown loach in the aquarium to lay on its side, or swimming up and down the glass?

Playing dead is normal in clown loaches. Though many fish owners wonder if this is a sick behavior, it is perfectly fine for clown loaches to sleep or rest, laying on their side motionless. Also, swimming up and down the tank is the way they play, which is also quite normal.

Q. Can clown loaches get too aggressive, or eat other fishes in the tank?

As mentioned, clown loaches are extremely well-behaved, peace-loving community members, and would not usually disturb or eat up other species. Though groups of clown loaches have been noticed pricking on the fins of other beautiful species including fancy goldfish, African cichlids, killifish, and guppies, it is very rare.
