Help!! My Fish is making weird unusual movements!

[AhuraMazda_JSB]

My fish is spinning around over it's belly at a very fast speed (around 2 or more times a sec), i don't know the proper name of the fish but i know it's a cichlid, i had the fish for 2 months and it has been fine, suddenly today it's all weirdo...

I'm scared it's gonna die, please help!

Well,as terrible as this is,it's really hard to help without more details.
What size tank?
Does he have tankmates?
What are the water parameters? (ammonia etc..)
What's he been eating?
How is he now

Sorry bout the lack of information, i never knew u had to state these

It a 150 L tank
He has 12 tankmates, all of which are absolutely FINE
All the water parameters are fine
He's been eating normal pellets, flakes
Right now he's dead, because i killed him, because that was the advice i got from the local Aquarium, they said it had a disease that was uncurable and the fish was going through pain, so in the name of god i killed it
