I just started my fishless cycle a Aqueon 40g breeder 36.2" x 18.3" x 17",I noticed it bows out a little..i bought it new last week,it doesnt have the center brace.and why it wouldnt have one and some would...is this normal on these tanks..
would you know the reason why40 breeders do not typically have a center brace, at least not the ones made by Aqueon.
