The floor tank I had been keeping my coldwater fish in ruptured last night and is no longer watertight. The fish were evacuated to a 10 gallon cooler and a 12 gallon tote. The cooler holds three 3" koi, a 3" pleco and a 2" goldfish, and is filtered by my Whisper 30-60. The tote holds about five goldfish ranging from 2-2.5" and is filtered by my homemade UGF. I would prefer not to be adding any more enclosures until I get my 55 gallon tank, so I would like to know how long I can safely hold my fish in these containers. Would daily 10% water changes help? Thanks.
