Wow! That's bad! I had read everyone's complaints on another forum about how terrible the Tetra's were last sale, so I was expecting the worst when I went to pick up my 20L, but my hubby & I looked at several and really only saw one that had the seal coming loose at the top. Maybe we just got lucky. We did go on the first day of the sale, because I was worried about getting stuck with a bad one and I didn't want to make my hubby reseal yet another tank - even though he seems to be getting so good at it now. LOL!
I am really trying to resist the urge this time around....but I did see someone on CL selling juvenile axolotls for a decent price not to far from me, so the urge is strong!
