mine is a 3foot in lenght and 2foot in height tank, i use neon lighting ,internal type filter ,a heater and ofcourse an air pump etc...
firstly start with smaller tanks and some small fish like guppies and all those stuff and then gradually increase tha size of ur tank.
had kept almost all tropical varieties but presently i am having an silver arowana with a pair of black ghost as it's companion.
dont know their names ,sorry

Keeping anemones in a reef tank can be a challenge if you are not fully prepared.
Cultivating a nano tank can be an exciting challenge but unless you choose the right fish for your tank, you may be in trouble.
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.
