Hi, I’ve recently attempted to aquascape my aqua one nano 80. I’ve had some success so far but realised I’m still lacking in plants, so hope to plant a few more this week. I’ve put Tropica soil in to help. I’m trying to get Monte Carlo carpeting the front and sides. It’s been running 1 week with CO2. My question is do I need certain species anymore? I've 4 corydoras, 2 bristle nose plecs, 2 Siamese algae eaters and wondering whether I need them now?
