nickh Posted July 9, 2010 Report Share Posted July 9, 2010 Hi All, I have just transferred my 5 lemon tetras over to my small 19L tank that had been fully cycled, when tested before moving fish it was Ammonia- 0 Nitrites- 0 Nitrates- 10 Ph- 6.5, not too different to the community tank they came from (about 6.8) They appear to be breathing very rapidly and seem to have a swim bladder problem (not swimming the right way up/ not swimming at all) What could be causing this? since moving them (buy floating them, then adding water) i have lost 3 in an hour. They were fine in the community tank Thanks for your help Quote Link to comment Share on other sites More sharing options...
Jennifer Posted July 9, 2010 Report Share Posted July 9, 2010 Fish sometimes swim erratically when the temperature is off, although there is a pretty wide margin of error for that. Could be toxins from something else, might pay to do a fairly large water change (with a tank that small you could even replace most of it with water from the community tank). If I were you, I would get the fish out of that tank and put them in a bucket with water from the community tank while you figure out what is wrong.
