completely unintentionally, I left about 4 sword fry in a tank with about 10cm of water, gravel, no heater, no plants and no food :oops: and when I got round to cleaning it about 10 days later they all threw me evil looks, complained about the cold and were generally unappreciative about the fact. But STILL ALIVE
I apologised profusely and moved them to be with their brothers and sisters. :lol:
That was in a tank by the backdoor in the middle of winter. So, who knows, swords may be okay outside in the summer :-?
