Rachel Hardacre –
Received the blue pelagic porcupine puffer in good condition. It’s active and shows interest in feeding. The tank setup was stable, and the fish has adapted well after a few weeks. Requires a large tank and careful monitoring due to its semi-aggressive nature. Worth the investment for experienced aquarists.
Rachel Hill –
The fish arrived healthy and has been active in the 75-gallon tank. It doesn’t eat coral, which is a relief. Needs consistent feeding and a well-maintained environment. Not recommended for beginners due to the intermediate care level.

Great addition to a deepwater setup. The fish is curious and shows natural behaviors. I’ve maintained water parameters carefully and it’s thriving. Only issue is it can be territorial with other fish, so tank mates should be chosen carefully.
