I think what pablo is trying to say is his water hasn't been changed in 8 months, by some act of god the 32 fish managed to survive till pablos amigo turned off the central heating in his house . . . mexican fish refuse to swim when its cold :thud: so 24 hrs later when pablo was satisfied with the water conditions in the tank he decided to kill another 30 fish.
Moral of the story - Just Say NO -
