I'm saving for a 180 BUT my husband said we can try building a 8' x 2' x 20" plywood in the basement! He has some spare time this winter and can help me with the construction. I was floored when he suggested it because he really dislikes my fish. I think he just wants them out of the living room and into the basement, but hey, if I get a big tank then I really don't care where in the house it's at!
My biggest is my 55 gal that I just picked up last month. I just started getting into the hobby so give me some time I'm still living in a rental apartment so space, size and money were all issues. I will also be picking up a 20gal long planted tank and I should have a 5.5 gal, but it hasn't come in the mail yet (even though it was shipped out LAST monday....shady...)
