I am interested in doing a small 5 gallon tank with a single CPO and had some questions. I am not really all that interested in maintaining another planted tank and was wondering if it would be alright in a 5 gallon with fake plants and some rocks/hiding areas. If not what's a cheap way to go? I already have a small 5 gallon acrylic tank and want to make use of it as I got it for a good deal. Thanks.
