One of the most talked about stories on Spanish social networks demonstrated what it takes to bring neighbours together. The story's thread has made Pesesín the most famous goldfish in Spain.

On July 2, 2017, the residents of a block of flats in Gijón (Asturias, Spain) stumbled upon a goldfish bowl, a tin of fish food and a note in the hallway of their building. The note said:

Me voy unos días de vacaciones y no me dejan llevar a PESESÍN. Necesito vuestra ayuda para que le deis de comer, solo se le debe echar una vez al día. Dejo la comida y un cuadro para saber cuándo comió.

MUCHAS GRACIAS

I'm going on holiday for a few days and I can't take PESESÍN with me. I need you to help feed him, he only needs to be fed once a day. Here's the food and a chart to keep track of when he was fed.

THANKS A LOT

On the note, there was a chart that the neighbours could use in order to record when he was fed, which started on Sunday July 2 and ended on Thursday July 13. Without any hesitation, the neighbours adopted the goldfish, feeding him and noting each feed time diligently. They even left notes and instructions for their fellow neighbours:

‘¡No echar tanta comida!’
‘Agua cambiada el viernes 07/07′
‘Se le cambió el agua a Pesesín el lunes 3 y mientras tanto estuvo nadando un poco en el lavabo (1°D), pasolo estupendo!’

‘Don't give him so much food!’
‘Water changed on Friday 07/07′
‘We changed Pesesín's water on Monday 3 and whilst doing so he was swimming for a while in the sink (apartment 1°D) He had a great time!’

It also seems that on Sunday there was a mini-crisis when Pesesín's food ran out. But this was quickly resolved by the neighbours in apartment 4°, who bought another tin.

One of the neighbours, Nuria, found the story amusing and decided to share it on Twitter:

Alguien de mi edificio se ha ido de vacaciones y ha dejado en el portal a su PEZ para que el resto de vecinxs lo cuiden mientras tanto pic.twitter.com/WE70D1TXjo

Someone in my building has gone on holiday and left their FISH in the hallway so that the rest of the neighbours can look after him

Y nada es muy guapo y está ahí a lo suyo nadando tranquilo etc y todo el bloque está intrigadísimo con quién lo ha dejado ahí.

— Nuria (@Nuria_GMz) 11 de julio de 2017

He's a very attractive fish and is there swimming peacefully whilst the whole block is extremely curious as to who left him there.

What Nuria didn't expect was the response that her tweet received. It quickly went viral, with more than 60,000 retweets and 100,000 likes. Soon, Pesesín became a trending topic on the social network — and not only in Spain. The tweet also grabbed the attention of users from Argentina, Mexico and Colombia.

Many Twitter users reacted to the news by praising the community that looked after the fish:

Me encanta que vecindario más majo donde vivir que me mudo jajaja me encanta pesesin

— Estefania (@fanny15715) 12 de julio de 2017

Love this, what a nice community to live in, I'm moving there! I love Pesesín!

Quédate con la persona que te cuide y se preocupe por ti tanto como los vecinos de @Nuria_GMz cuidan y se preocupan por pesesín.

— guido (@GFioravantti) 12 de julio de 2017

Stay with the person that looks after you and worries as much about you as the neighbours of @Nuria_GMz care for and worry about Pesesín.

Me muero con la historia de pesesin! Todos los vecinos cuidando del pez de la vecina. Aún hay esperanza en el mundo.

— Carol (@srta_estivbi) 12 de julio de 2017

I'm cracking up listening to the story of Pesesín! The whole community looking after their neighbour's fish. There's still hope in the world.

Quando vuelva el vecino #pesesín tendrá un acuario pro con chorros, plantas y un Bob Esponja de plástico.

— Puropoliester (@Puropoliester) 12 de julio de 2017

When the neighbour gets back, Pesesín will have a new fish tank with jets, plants and a plastic Spongebob Squarepants.

Other users rightly criticised the recklessness of the fish's anonymous owner, highlighting — in some cases — the double standards we apply to animals:

Muy gracioso lo de Pesesín pero dejar el pez en el portal para que te lo cuiden los vecinos es tener un morro impresionante.

— Un muchacho (@AlexSegurola) 12 de julio de 2017

Very funny story about Pesesín, but you must have real nerve to leave a fish in the hallway for your neighbours to look after.

Muy bonita la solidaridad vecinal, pero la dueña una gilipollas irresponsable que no merece tener a su cargo ni a Pesesin ni a nadie. #Jeta!

— Rut Carrillo M (@Rilwenrut) 13 de julio de 2017

What wonderful solidarity among neighbours, but the owner is an irresponsible idiot and doesn't deserve to look after her fish or anything else for that matter.

Viva la hipocresía! Si #Pesesin hubiese sido un perro o gato alabaríais que lo hubiesen dejado en la escalera con comida???

— PeeWee (@PeeWeeTuit) 13 de julio de 2017

The hypocrisy! If #Pesesin were a dog or a cat, would you condone leaving them alone in the stairwell with food???

Esto es la versión beta. El año q viene os deja al abuelo para q lo cuideis entre todos.

— Soy un bot (ijo) (@CaosAzucarado) 11 de julio de 2017

This is just the beginning. Next year, you'll be left with the grandfather to look after together.

The national police also weighed in on the debate.

¡Siempre hay una alternativa al abandono animal! Un vecino caritativo… o toda la comunidad?.
Besines para #PESESIN ?

? #animals https://t.co/xLrwq6b80d

There's always an alternative to abandoning an animal! A caring neighbour… or the whole community?. Neighbours for #PESESIN ?

Pesesín himself, who has a Twitter account, gave his opinion on his unexpected rise to fame:

Splash.

At the end of the week, we met Yurena, Pesesín's owner. Stunned by the fame that her pet had garnered, she explained her side of the story during an interview with the Spanish TV channel Cuatro TV, in which she said that a trip came up with her parents, but she couldn't take the fish with her. After asking friends and acquaintances [to take care of him] without any success, she decided to leave him in the hands of fate…and the solidarity of her neighbours.

After seeing Pesesín looking well, Yurena felt immense gratitude towards her neighbours and wanted to express her thanks by leaving another note in the same spot that goldfish bowl had been during her trip:

A thank you note from Pesesín to the neighbours that had looked after him so well. Image shared by Yurena Sabio on Twitter.

MANY THANKS TO ALL THE NEIGHBOURS!

On behalf of Pesesín and with special mention to those who changed the water and bought food. Although the food that was left was meant to last a few months and now I need to put him on a diet for a few days, he has loved getting to know you.

On Pesesín's story's thread, a Twitter user took advantage of the good nature that the police usually show on the microblogging site, making this suggestion:

¡Hola,@policia!

Me gustaría que la próxima trama policial que tengáis la llamaseis «Pesesín».#elcasoPesesín

Hello, @police! I would like you to call the next police investigation you have, “Pesesín”.#Pesesíncase

To which the popular account replied:

???… ¡¡Trato hecho!! Prometemos la operación “Pesesín” cuando pesquemos? un pez gordo!! https://t.co/hsuI9rvib2

— Policía Nacional (@policia) July 13 2017

???…Done deal! We promise to call the operation ‘Pesesín’ when we catch a big fish [a big criminal]!
