Oh yeah. I bought like 60 odd exotic ones (the blue & red ones that look like bettas) came back later that night and they were fine. Somehow I'd had fish added, a clownfish looking one, and a yellow & black one and a blue & yellow one. No idea where they came from but that was cool. Fed them, came back next morning all my betta looking ones are dead. Other ones aren't. Miffed. Didn't feed them, came back that night and the rest were all deaded too
Someone needs to tell the game makers that fish CAN survive more than one day without being fed. :evil:
