Here is the tank.
96 liters = 25 us gallons = 21 imp. gallons
l 80 x h 40 x w 40 cm = 2.6 x 1.3 x 1.3 feet
pH 7, soft water, temperature 24C = 75F
70% sand / 30% gravel
1x 18W daylight fluorescent. Not possible to add lighting.
Fishes: panda corys and glowlight danios.
I think that java fern on the right doesn't look good enough and I'd like to replace it with something. But what would survive in low lighting? It would also need to be quite hight so it will hide the filter. Is there any suitable plant?
