Good Afternoon, This isn't my first time hear but hopefully this time it will be with a great deal more success! I have had tropical fish all my life and recently purchased a RIO 400 which is currently sitting clean & empty in my front room! I am going to take the dive and get the bug but first want a few tips and pointers! Sorry for all the questions but here goes... As this is in the front room of my two bedroom flat I unfortunately cant have a quarantine tank, so would people advise to having discus only and stocking all at once? Also the wife is against the BB look so am thinking about sand and some bogwood with the possibility of a few plants, my fear with a planted aquarium is that I really want to make sure the discus work and am worried that having live plants will add another thing for me to think about... but I firmly believe that discus deserve more then plastic plants so that is a definite no-no... any advice? on this also what do people find best for a 'background' ? last one (for now ) is water. Is a RO unit necessary? or a HMA? as stated I am slightly limited to space so cant store huge amounts of water all the time so need to figure out the best way to make it work.... thanks guys!!
