Can a Bristol shubunkin (2 inch long excluding tail) live in a tropical fish tank for 6 weeks. Fish was bought last week and put in 100L tub outside but we have a cold snap (aitr temp 1C). I found him today floating on top and very sluggish. Gold fish bought at same time had died. Shubunkin is now inside in a Tupperware tub and has perked up. Can he room with my tropical fish (temprature76F 24C) until the weather warms up? The alternative is a bucket.
I am experienced with tropical fish, but know nothing abut coldwater fish. I don’t think a disease is involved.
Can I keep this sort of fish outside (they were sold as pond fish) in a 300L tub?
Hi, A temperature of 24 is going to stress the shubunkin excessively, especially as it has recently been exposed to very low temperatures - you might end up allowing a disease such as whitespot to come to the fore and spread to your tropicals. I would keep it on its own at room temperature until the spring/summer, when it can go back outside - you can get an adequate holding tank with equipment very cheaply these days (second hand set-ups from the local Free Ads paper might be the best way to go). Shubunkins can be kept outside without any problems usually, but in a small tub like yours make sure you switch off the circulating pump in the winter, so a layer of slightly warmer water can form on the bottom, where the fish will stay in a semi-dormant state until the weather warms up again. Hope that helps, Marc
shift the temp no more than 4oF per 24 hours until your fish has acclimatised. Remember your goldie produces much more waste than your trops and could poison them - make sure you do clean up if and when you introduce into tropical - its certainly not ideal, but better than nothing.
