Singer Jason Derulo faces backlash after revealing details of an in-home aquarium during a house tour in California. Multiple outlets report that the entertainer installed an underground or underfloor tank designed for sharks and stingrays in his mansion, which includes a visible viewing area. The Independent describes the setup as an “underfloor” or underground shark and stingray tank and characterizes some reactions as criticism that the arrangement is “cruel.” The New York Post also reports negative public response, noting backlash and framing it as setting a bad example. The reports tie the criticism to the decision to keep sharks and stingrays in a private residential tank, with commenters expressing concern about the animals’ welfare and the implications of keeping them in such conditions. Across the sources, the core facts are consistent: Derulo shows or discusses the shark tank as part of a home tour, and he receives public criticism in response. None of the provided coverage includes details of any official investigation or response from Derulo.
