the deal is 4 dead fish, i think i added the water too fast though i did put conditioner in it. another thing the fish seemed to have possibly thrown up the night before last. the tilapia I was feeding them was less than 4 days old. could that be it? they had a white film on them when they died but were not slimy at all. let me know what i did wrong, this sucks!ok. So whats the deal?
What temp WAS the tank and what temp is it now?
Did you dechlor the water before adding it?
Fresh water should not harm your fish so there has to have been something wrong with they way you went about the waterchange.
What are your water params now? ammonia/nitrites/nitrates
