sorry to hear... but if all the tigers shared the same tank at any time in the past, then the paracites could still be present, in another fish/host (waht vaine111 said)
I always try to avoid meds, but based on the recent deaths, i would blast the tank with anti paracite/bacteria meds. then wait 3 days, then do 30% wc daily, until tank is flushed 100%. if u dont want to use meds, then salt, up temp, then do 30% wc daily, until tank is flushed 100%.
best to be safe, following so many dieing not too long ago, something is lurking in water or fish.
hope everything settles for you. dont htink thers much more you can do
