Aquariums in Bristol and Plymouth have spoken to ITV News about the 'frustration' of seeing zoos, safari parks and some non-essential shops reopen when they are to remain closed.
It comes as an announcement this week brought good news for zoos and safari parks who can open their doors as of Monday 15 June, whilst indoor attractions like Aquariums must remain closed, something which they say could have serious financial implications.
The National Marine Aquarium in Plymouth costs ten thousand pounds each day to feed and care for its five thousand animals.
Without being able to welcome visitors, the aquarium has lost more than one million pounds since closing on the Monday 20 March.
It's now urging the Government to allow it to open on or before Friday 4 July.
Nicola Bridge, Head of Conservation at Plymouth's National Marine Aquarium, told ITV News: "It is still difficult when we know non-essential indoor things like Ikea and Primark are able to open from Monday and we're not, even though we have a lot of space."
She said what the aquarium needs from the Government is a 'firm opening date'.
The Bristol Aquarium shares the same struggles saying it's 'daunting' having to run costs with no income coming in. But they don't want to ask for handouts.
General Manager Fenia Vitali said: "We don't believe it's right in going to the general public, morally, and asking them for financial donations because we're not a charity.
We don't want to drain government funding. We want to fight for our survival and we want to do that by opening the doors."
Both aquariums say they're ready to reopen, with a one-way system in place and other measures including extra signage, hand sanitising, customer charters and timed entrance slots.
Roger Maslin, CEO of Plymouth's National Marine Aquarium, told ITV News: "We're planning for July 4th, then we think we can get through this. But if there is further delay that becomes critical for us, our plea is please come and see us."
