Help me please. we have just got our tank about 2 months ago it is 90 litres with 3 goldfish 2 orandas (1 is tiny) 1 guppy and 4 tiny little fish. We have put in it two real plants and it is turning green the water looks clear but the glass is really green. the water was cloudy but is now ok as we treated it. should i take the plants out or leave them. with regards to my last post the fish i thought was ill is now ok. does anyone know if a male guppy needs females as our one died last week and he looks lonely as they stuck together all the time.
