this is a 20 gallon tank, about 9 months old. it has 9 serpae tetras in it and 2 chinese algae eater. The water perameters are all perfect and have had no problems. i have a 30 gallon filter on it, a bubbler and a heater. I still feel sad looking at it as it has no plants and just a gravel bottom. I was arrogant to say the least when i first created it and want to improve it. i have little experience with plants but if anyone has ideas or suggestions please reply. i also know that the CAE get really big so I don’t know what to do there
