The Puffer Forum

I just wondering about puffer such as Tetraodon erythrotaenia. If they stop eating could it be relate to water quality like ammonia? Or what other reason that the puffer stop eating? Thanks in advance.

It could be lots of reasons.
One could be water quality, like amm. poisoning, nitrite poisoning, IP's, med's that you used in the tank, getting picked on by other fish, nitrates too high causing nitrate poisoning. Puffers are very sensitive to alot of stuff that other fish may not have problems with. Without more information there's no way to tell why your puffer stopped eating. If that's the case you really need to post in the hospital section and answer all the questions in red. If it's just a general question, there's a load of different reasons.

All the Qs above in red can cause the puffer to not eat. Try to answer as many as you can so we can help.
