I am a hobbyist and have recently managed to set up a tank measuring 2.5ft x 1.5ft x 1.5ft which has two filters one is a SOBO 1000F and the other one is the normal black medium filter with aeration. I am also using an aquarium heater. I have 10 big goldfishes - fantails and orandas. I loved the planted aquarium set ups and would like some suggestions on how to start and what to put in it. currently there are medium sized gravels in the tank and a few show beach shells. any help will be much appreciated - cheers!
