t5Nitro,
Thank you for inquiring about our beautiful Regal Angel Fish before adding one to your aquarium. As specsirl stated in their post, it is best to add the Regal Angel Fish to a well-established tank. Our LiveAquaria Quick Specs box explains they need a minimum tank size of 100 gallons and they are classified as Expert only. We guarantee that ALL aquaria species we offer will arrive alive and in good condition. However, because of the increased level of care required for this particular species, it has been designated as "Expert Only," and it is recommended that only the expert marine aquarist, zoo, or research institution purchase this species.
Please feel free to call us at 800-334-3699 with any further questions you may have.
