Axolotl not eating for 3 weeks

[CrystalLin]

Hey guys my axolotl(got him for around 4 months) hasn't been eating or pooping for 3 weeks now. I fridge him for 3 weeks straight and he is still not pooping. I feed him shrimp and pellets usually. His stomach is bloated. He refuses to eat. Before he got sick, the 20 gallon long tank has 0ppm of ammonia, nitrite, nitriate. Water temperature is at 18°C. I have no gravels in the tank. His bottom of the stomach has this white little circle. He is not getting better. Today when I checked, he seems to lean on to the other side more( loose balance) I don't know what to do now. Does anyone know this situation??

It's bloated, could be anything from liver failure to an intestinal blockage, it needs a vet

Thanks for replying. I have been looking for vet in NYC. I don't know if they are specialized for axolotl. Do you know any vet in NYC?
