Kuhli Loaches need a healthy, balanced fed tank water with a small amount of food. They prefer tank water that is a little bland but still has some flavor. Ideally, your water should be less than 80% water changes while being well-maintained. If you are unsure how to go about maintaining your tank water, it is recommended that you try keeping fish in your home aquarium first before attempting to raise them in a reef environment. Remember to provide your fish with the best environment possible, from the water conditioner to the food you feed them, to help them thrive.
