The risk a power cut is posing to some of the most exotic species at the National Sea Life Centre in Birmingham has receded, say managers.
Power has been restored at the National Sea Life Centre in Birmingham nearly 24 hours after a blackout left its exotic species at risk.
Staff have been able to connect power generators to boilers and boost water temperatures to reduce the problem.
The centre was one of the last to be reconnected after a fire at an electricity sub-station.
Managers had said animals were at "grave risk" after the blackout, which initially affected 8,500 properties.
Managers had feared animals were in danger because the blackout caused the water temperature in its tanks to fall.
The centre is one of eight properties still without power, caused by a sub-station fire early on Saturday.
Up to 8,500 homes and businesses in the city centre were originally hit by the power cut early on Saturday.
Electricity providers, Central Networks, have confirmed the power is expected to be completely restored sometime between 0000 and 0200 GMT on Sunday.
Before the power was restored, just after 0100 GMT on Sunday, Sea Life Centre staff managed to connect emergency power generators to boilers, which enabled them to boost water tank temperatures.
It seems ridiculous that the power in a centre like this should still be out approaching 24 hours later Ian Crabbe, National Sea Life Centre
Earlier manager, Ian Crabbe, told BBC News the work had left the centre's animals with much better prospects.
Mr Crabbe told BBC News the prospects for the centre's animals were "much better" after the work done by staff.
"They have managed to divert more power from the generators to the boilers and we now have water going back up in temperature," he said.
"The power supplies to the centre are still out, but we have been told they should be restored in the early hours of Sunday, which will mean by then we've been 24 hours without power.
"But fortunately there's not the same risk to the animals there was earlier."
Species like the giant Hawaiian turtle and the black tipped shark had been at particular risk because of the drop in temperature.
However, Mr Crabbe said despite this Central Networks had not given a full explanation to him as to why the centre's power had not been a priority to restore.

"It seems ridiculous that the power in a centre like this should still be out approaching 24 hours later," he added.
"Fortunately there's not the same risk to the animals there was earlier," he said.
A Central Networks spokeswoman said however, it was "unfortunate" that it is simply down to the centre's location on the electricity network.

"Following the fire, our first priority was to re-connect properties and the quickest way to do this is to divert them to another part of the network, which for most places we could do quickly," she said.
However, Mr Crabbe said despite this electricity suppliers, Central Networks (CN), had not full explained why the centre's power had not been a priority to restore.
"But unfortunately there were some, like the centre, that we just could not divert and permanent repairs have had to be done before they can come back on."

She said engineers have been working at the sub-station since 0500 GMT on Saturday.
A CN spokeswoman confirmed the power had been restored.
