newbie here so appreciate all the advice given. currently have the following in my tank: 2 pink danios 2 leopard danios 1 black molly 3 Guppies standard multi coloured gravel - looking to upgrade to a black or darkish brown substrate. standard corner filter - will we changed to something more appropriate/as advised spider wood and some rocks. I am looking to change the substrate and add some real plants, can you guys give me some pointers as to what plants to use. I was thinking java moss on the spider wood, what would be the easiest tall species to start with. Can I put bolivian rams or blue rams into a 2 foot tank?
