Check the water chemistry. This is done using a liquid home test kit or by submitting a sample for testing. Most pet or fish stores will do this for free or for a small fee. Ammonia and nitrites should be at 0 ppm and nitrates can be 40ppm or less. Partial water changes can be done to stabilize chemistry and maintain water quality. Use only aged or conditioned water that is temperature matched to prevent stress or shock. Try soaking food in garlic juice to stimulate the appetite. A 2-3 day fast followed by hand feeding bits of cooked and shelled green peas or spirulina may also promote regularity.
