a friend of my neighbour went and brought one of those 5 gallon starter tanks 2-3 days ago, brought gravel and fish and went home with it all. filled tank with water from tap-no dechlor,dumped gravel and 3 goldfish in and is now complaining that her house smells like a dirty nappy. my thoughts on this were maybe an ammonia build up,but then i thought no coz its too soon,so i asked her what filter she runs and she said i dont coz its cold water so it doesnt need one :headshake2: no matter how many times i tried to tell her that the tank needs to cycle,which yet again ended up with her telling me only warm water tanks need to sit with no fish in them (and yes i did try to tell her briefly what a cycle was) there seemed no way of getting through to her. all i keep thinking is poor poor fishies :headshake2: does anyone know of the briefest way i can put it to her about what cycling the tank does,maybe if i can blurt it all out fast enough she wont be able to interupt and tell me otherwise. i am considering bringing her round to see my goldie tank so she can see happy healthy fish instead of the 3 cramped into her uncycled, unfiltered, stagnant pot of water :mad2: its the usual £1.50 goldfish is cheap to replace theory i think.
