I'm just starting a new aquarium after many years of not having one. So far I have a 30 gal tank, Eclipse 3 Filtration System - that's it! I have ordered natural river pebbles and gravel for the bottom, I've ordered two deep purple Mystery snails (1. because they are very pretty and caught my eye and 2. I know they can keep a tank really really clean!). Both will probably arrive within the next week. I'm looking to order 3 trios of Moscow Guppies (a blue, a green and a purple). I've heard from people and read articles that say to add sea salt to the water - just a little bit - to promote breeding, is this necessary and why? I never did with other guppies I raised and believe me I had no trouble, they did just fine by themselves (lol)! Also what types of plants would be good and can I mix silk plants with real ones? I'm going to finish setting up the tank (water,etc) today so it will run for 3 - 4 days before I get the snails. I won't be getting any fish for at least another 2 - 3 weeks unless I get some gold fish to season the tank first. I'd welcome any suggestions.:newbie:
