Good Morning!
I recently got this little guy assuming that this puffer is a Diodon Holocanthus. However, upon receiving him, I noticed some features such as the shorter spines on him that are making me also think that he could be a Diodon Hystrix. The vendor I received him from told me that either species could be given, however I believe they look similar in their juvenile form and they vendor was not 100% certain.
Is someone able to confirm if this puffer is a Diodon Hystrix? Other resources have told me that the Hystrix is known as the Giant Puffer, and can grow significantly larger than the Holocanthus by sometimes double, which I would not be able to accommodate for in my tank setup. Thanks!
