Set this Tank up last month. Got the tank for cheap at a garage sale and Have been playing around with it. Finally got some Jack Dempseys in it this past week. Put 6 feeder fish in there to see if the Jacks would do anything. One died, but it had nothing to do with the Jacks, they are treating them just like any other fish. The Jacks are pretty small right now, so I'm not surprised. This is my first cichlid aquarium. Read up on Jacks before getting them and have a general idea of how to take care of them. Any tips on the tank would be great.
