Following a fertiliser explosion at Highlands Farm on 24 July 2026, Coral Passion has stopped trading from the site. Our insurance claim with MSIG Europe is still ongoing, but despite our efforts it does not look promising, and the future of the business is uncertain. Thank you to everyone who has supported us. I am still available & working on aquarium installations and maintenance. For more information, please contact tony@coralpassion.co.uk.
