Hi all, I'm Sue and I live in DC. I'm new to aquarium keeping although my dad always kept freshwater tanks when I was little. I have two boys in elementary school and am starting a tank with them in mind. I have a 20 gallon long tank with just a few male guppies while cycling. I'd love advice on a good mix of species for a small tank - not necessarily cichlids (are any suitable for a tank this size?) but am open to a variety of freshwater species. I love all aspects of gardening and houseplants - it's actually fellow plant lovers that have gotten me interested in keeping an aquarium. I'd love advice on plants as well. Last reason for joining - - I'm in a Facebook group focused on aquariums but wanted to be part of a local group for resources on buying/trading locally and dealing with our lovely DC tap water. Glad to meet the group!
