I have a 20g high, which will be planted. The filter is an AquaClear 50. I have had bettas in the past, so stocking has never really been an issue. I'm fairly new to community tanks. I used AqAdvisor, which I have heard is not always accurate. Here is what I came up with: 1 Dwarf Gourami 1 Male Guppy 2 Female Guppies 2 Male Platies 5 Female Platies 3 Horned Nerite Snails Is this ok? If not, I'd appreciate suggestions! I have sand substrate. Should I get some MTS? By the way, please ignore my aquarium info. I haven't updated it in a long time. The tank is currently cycling.
