Hi guys I have 2 pretty small goldfish 1 shubunkin and 1 fantail I was thinking about putting them in a bigger tank so they can grow I was wondering could I put the 2 of them in my 240 litre it only has 1 three spot gourami in it at the moment could I add them and put the temp to abt 72 - 73 degrees or would the gourami nip there tails and the temp be to high
