I don't mind at all! :) Currently, we have two twenty-gallon tanks: one community and one aggressive. Unfortunately, all but two of the aggressive fish are dead, so we're in the process of upgrading to a 50-gallon. ("In the process" meaning that Bobby is looking online for tanks and stands as I type this!) The aggressive tank was also a mistake to buy: the filter is annoying, and it's already not working properly, and it's only a year old. So we're really looking forward to upgrading ... plus, Celegorm and Maedhros are complaining that they need more room! ;) Hopefully, merging the two tanks won't spark a kinslaying!
