Hello ! I'm a new member in this forum. My tank is small one with only around 60l water capacity, four gold fishes of 3 inches long, and a few plants such as anubias & java fern. I don't have a CO2 system, but have an external filter (300 l per hour) & lighting system 0.4 watt per litre. My tank substrate is gravel only, and water temp is around 26-28 degree C. Pls advise what other plants can co-exist with my gold fishes and they can consume a lot of plant nutrient & inhibit the growth of green / green blue algae. I'm grateful if someone can provide any relevant links which is worth my reading.
