idea for 20 gallon

[mrtian97]

I have 120 gallon reef tank and now I have 20 gallon that available (used to be FW tank with parrot fish for 8 yrs which died recently). The 20 gallon has basic Hang on Back filter and heater.
Any suggestions of what I should do with this tank (no light).

Looking for low maintenance with manual top off

Thanks

Were you planning on buying a light for the tank at all? If so, a zoanthid garden would be fairly easy to maintain. If not, you could always stock it with various shrimps, hermits etc. An invertebrate tank so to say. GL.
