2.5 foot tank. T5 lights. Bubble curtain. Filter/Pump.
Don't buy too many fish until your tank is stable. Angel fish grow big :) oh and snails get out of control very very quickly.
3 x Angels, 3 x Darts, a small Yabbie I rescued from a pet shop and a few other things. The Yabbie likes to re-arrange things in my tank.
A few live plants that my snails are eating :( also a printed background.

When you see signs of stress in your fish, you can then take steps to identify the source of that stress and then to resolve it before it becomes a major issue.
If you're looking for a unique way to stock your new tank, give freshwater shrimp a try.
If your fish is suffering, you may want to consider euthanasia as an option to humanely end his pain.
