i know its a bit premature but for Christmas iam planning on getting a 55-90 gallon aquarium, dont know what size yet because iam planning on buying a used one. My problem is i dont know what to put in the tank. Here are a few thing i know; it's going to be freshwater, and have silk plants, larger rocks and driftwood. I dont want a hundred small fish or a couple huge fish, nor do i want overly agressive or shy or slow fish or cichlids. I would like it to be kinda like a biotope aquaria (fish from the same location). The fish must be fairly hardy and not that expensive. All sugestions are welcome, go wild! Thanks
