Hi I am new here and need some advice. I have one tank already an 80 litre with endlers and ember tetras that is doing well after some ups and downs I am now cycling a new 150 litre tank that once cycled I was thinking of stocking with male guppies Cory's and either Molly's or blue rams leaning more towards the rams but I am not sure of the amounts of each of these fish to put in or if the tank is even big enough to hold such a mix in addiquate numbers. Any advice would be appreciated
You need first to find out how hard your tap water is. You can get a good idea from your supplier's website where you can put in your postcode and get a water report including hardness. That will determine which fish you can keep as guppies and mollies like hard water and cories and rams like soft water.
There aren't any typical bottom-feeding fish that do well in hard water, there is the Tanganyikan fish, Synodontis lucipinnis......a group of those would be OK with mollies in your water and that size tank. You could have six or so mollies.
