Hi everyone!, What do you think about this hardscape? This is a 20 gallon tank 80cm long, 40 high and 23 cm deep. Substrate is AS and at the bottom Power Sand Special. Planning to plant there Glossostigma in foreground, Blyxa in the middle (just between the roots), left and right corner Rotala indica and at the back in middle Vallisneria nana. What do you think? All sugestions are welcome!
