Hi I have been running a duo deep 600 for about year and a half. Much learnt over the year, least not the bright blue gravel I started. I have not restocked my fish a little while now. Current setup has 2 Opaline Gourami Harlequin Siemese Flying Fox Bristlenose Catfish Swordfish Amano Shrimp current setup Some plants have changed. I have picked up an ex display osaka 260l, so I will look to keep most of the current plants. I have a plants alive 24" collection coming tomorrow. Just working out how to set the tank up Any ideas, on the setup I'll post the pictures of the bogwood and green quartz i picked up will be great.
