Well i just got back from newcastle, and the fish are all ok, well.. the ones who were still alive when i left. Im about to transfer the yoyo loach and the BN back to their tank as they seem to be doing ok after 3 days in a bucket by themselves with a little salt, a heater and an air stone. The two rosy barbs who were floating around the surface didnt make it, and 5 harlequin rasboras and 3 odessa barbs also didnt make it. Thanks for all your help and hopefully the survivors will be ok =)
