i have a small corner tank - around 6 imperial gallons - that is obviously too small for goldfish.
but i know i've read somewhere that you can keep some small tropical fish - like tetras or mountain minnows in an unheated tank - does anyone know if this is really true??
the tank is in a really warm room - so the temp never goes below 23 C - so its not that cold anyway. but i've only ever had coldwater fish - so i'm not 100% sure!
dont want to do anything cruel - so if anyone could advise me - or point me towards a good place for info - that would be cool.
i've tried looking - but only ever find info in regards to them being in heated set-ups??
