I just got a 20 gal tank, hood, light, thermometer, penguin bio-wheel filter, and heater for $15 ! I currently have a 50 gal setup with cichlids, a 30 gal set up with more cichlids, and two ten gallon tanks fro raising babies that the cichlids have. I have no clue what to put in this tank, any ideas would be nice. Thanks in advance
