Hello, I have just joined this site as I came across it looking for advice but it all looks very friendly and I am looking forward to recieving and giving advice on it. I have just bought new tank which is 360 litres(about 80 gallons). I am intending to make it tropical so looking for advice as I have only kept coldwater fish or tropical community tanks before. It came with a juwel unifilter 1000 which I assume the correct capacity for the tank but I need purchase a heating system still. What wattage would I need and does anyone have advice for brand? I thought to help bacteria develop I would place ceramic balls as the substrate but am unsure whether this will be beneficial or not? I was not sure whether to go for a planted aquarium or not as the fish I would like are large and many would eat plants but I have read that plants help with nitrate so would it still be worth a try and if so how do i start a planted please? It is UV lighting so plants should grow easy? Sorry this so long but I thought I should include detail and have many queries about aquarium. I would like one oscar fish and a arowana and was considering some silver dollar fish. To keep tank clean I would like a common plecostomus and catfish(advice on species appreciate) and a blue lobster. Would this be appropriote mix for tank? Thank you for read all and really appreciate any help you offer
