Hello everyone, I registered on the site a few weeks ago, but didn't see this board until today. I am really new to this aquarium thing and am loving it!!! I (we, my brother and I) have 2 tanks. I have a 7 gallon with 3 platys, 2 guppys and a small rubber lipped pleco. My brother has a 20 gallon with 6 tiger barbs, a golden nugget pleco and a rubber lipped pleco. The 20 gallon has been running for about 2 months and the 7 gallon for about a month. I presently live in Toronto and have already received wonderful advise from some of you guys!! Thanks for all the help, don't worry, there are a lot more questions to come hehehehe!!
