Bro dun get me wrong. many of the ppl I know keep outdoor for Tvr there are way to overcome temperature.
On the day u do fumigation u may wan to remove ur Tvr in to ur house for temp for one to two days, u may make use this two days to fast ur fish and do 100% cleaning of ur tub. After u fumigation.
Anyway I dun think anyfish can take the fumigate medi. As I know that is toxic to any pet... Let me know if I am wrong
