So I was going to start a new aquarium within the next few months. I have a 20 gallon long tank and a stand to put it on, I have gravel....and that's about it. I need a hood, lights, a cheap but reliable and efficient filter, an aeration system if it's not included with the filter and plants/decorations. I want to put in a few Cockatoo Dwarf Cichlids and a few other dwarf cichlids with them. The problem is that I don't have very much money and I at least need a filter and light to start the cycling.....any suggestions on cheap equipment?
