I am I the only person with a 23 gallon long? Actually my sump is a 23 gallon long aquarium. When I was building a sump I went to one of my lfs that always has used tanks and equipment for sale. With that in mind, I was going for a 20 gallon long and happened to find this. Petco never has the $1 a gallon sale when I need it. Anyway this was the only tank with these measurements in the store. Probably has close to 200 used tanks in store. So as I read about the 23 long apparently it may be more popular in Europe. I just curious if this is a old size that wasn't popular, or just odd size!
