110 Bishopsgate was designed to feature a concierge-style entrance and reception area, incorporating a aquarium containing around 1,200 fish. The aquarium is the largest privately owned example in the United Kingdom and contains over 60 species of fish in an entirely sustainable ecosystem; the species were selected by expert biologists and animal curators to ensure compatibility and adaptability to the environment. The tank is attended to by a team of two full-time fish attendants, who feed the fish a diet rich in natural ingredients according to their requirements and monitor the tank for water chemistry and fish health, and two to three part-time divers who clean the rockwork and glass regularly.
