The bizarre but beloved Bedford-Stuyvesant street aquarium, born in the summer, was destroyed Tuesday during an FDNY fire hydrant inspection — but locals are already cleaning up the pieces.

Nickel-sized goldfish flopped on the Brooklyn sidewalk after firefighters turned off the fire hydrant — which has been the source of water for the makeshift pond since it surfaced in August.

In a video shot by Hajj-Malik Lovick, who helped build the fish pond, a bystander can be heard asking the smoke eaters “will they survive,” referring to the fish left in the murky water.

Another firefighter further explained that the hydrant inspection was a routine six-monthly check to see if the water was still working.

They also told outraged locals that a leak in the colder months could spell doom – resulting in frozen pipes that would render the hydrant unusable when it was needed in an emergency.

“(The fish) isn’t going to survive, look what he did,” Lovick said as he zoomed in on the water, “All that dirty water. They knew what they were doing. No respect.”

The fish did indeed die.

Aquarium enthusiasts woke up Wednesday morning to see “more than 100” dead goldfish that did not survive the abrupt deterioration of their ad hoc biome.

But the sun would not set in the city aquarium.

Organizers are already revamping the construction of the prized lake to prevent future disasters.

Local contractor David Jones lives with his brother around the corner from the monument. The two were working Wednesday evening, using caulk to seal a professional-grade pond liner to the bottom of the makeshift tank.

“We’re trying to make it waterproof so we don’t have to worry about it running all the time,” Jones told the Post. “The fire brigade complained about running water. So now we’re going to make it waterproof.”

Architect Devang Arvind Shah, 44, also lives nearby and came to help.

“It should be operational tomorrow,” he told the post.

Another local resident, Sophia Buffa, said her father is visiting from Atlanta and was excited about seeing the Brooklyn sight.

“He was so excited to see it,” Buffa told the Post, “He calls me all the time and says, ‘What’s going on with the aquarium?’ Oh my God, he’s going to be devastated. He literally answered questions about it on Instagram.

‘He doesn’t even live here. But the magic of the aquarium reached him.”

Floyd Washington, one of the project’s co-founders, told the Post: “We’re not trying to mess with anyone or government officials — we’re just making sure we give back to the community we came from.”

Washington added, “This isn’t about the fish. This is about a community in a chaotic city.”

According to the FDNY, the actions taken Tuesday were in accordance with standard operating procedures.

A department spokesperson told The Post in a statement that the FDNY “did not take any action against the fish” and also “did not drain the pond.”

Instead, firefighters performed routine maintenance on the hydrant, which is expected to happen twice a year, the spokesperson said.

FDNY officials determined the hydrant was fine and turned off the water.

As for the colder months, organizers are currently trying to put a plan in place that will keep the fish safe, healthy and swimming.

“We are going to install heating elements in it. Solar panels generate heaters,” Lovick told the Post, adding that they will also add a cover to keep the snow and freezing rain from affecting the pond’s temperature.
