the thing is my dad said he doesn't want me to get any more heaters(i think im using a fair bit of electricity) at the moment there is a small comet goldfish in there and don't worry i will give it to our friend with a pond
asap.
no there isn't any filtratoin in there
adn replying to smallfry's comment about it being winter, if he looked my locatoin is australia and we are currently having the coldest winter we have ever had since i was born probably so the temp isn't usually that cold it can only get hotter1
