This is my tank. I lost almost all my fish after a water change and I am trying to scape it before adding some fish. I currently have a gourami which survived the tragedy and two guppies. This tank is outside my house where I have ample natural light and it is hot throughout the year here. I am new to planted tanks. I don't have Co2 diffuser. I am using a Boyu power filter and an air stone. I have planted valisneria mainly. Will I have to add lighting and CO2? Also suggest what fish I could add. Planning to add a school of Boeseman's Rainbow fish.
Also my DIY driftwood has some algae now. Please advise
