Well, I found another "pufferlover" here in my country, and we discussed a lot about F8. But you'll not believe... I was telling him what you've taught me about puffers. OMG, he keeps one puffer in a FW tank with cichlids, just measuring PH once in a while (BTW, PH 7
Food:
-brineshrimp (THE staple food)
-ground meat
-large Italian sausage
-dead fish;
Keep them in FW at neutral (7) PH and that's all, because they ARE hardy fish!!!
His fish has lived this way for one year and a half and it's still alive. And everything I learnt here and tried to say that could improve his fish livespam seems to sound like walrus and he said I should not trust in everything I read (but this IS the right place - PUFFER FORUM) - OMG, I cant' believe... But how could he trust me if my F8 just lived for 25 days and he keeps his for 1.5 year??? This whole thing was unbelievable!!!
Sorry for the long text, but I had to share this experience...
