I am probably one of the most blessed ppl in the world

HE bought my first upgrade for Christmas (I chose it), & later picked up my baby O from another mfker.. seeing the sellers' adults was his first real understanding of how big mine would get (I already told him & showed pics, but he pays as much attention as any other man ;-)
I had to put O in a small tank, husband started feeding him crickets= sparking his interest.
but he's always fully supportive. goes out of his way to pick up my 'whatevers' on his way home from his work trips!
I don't really recommend the get it & ask forgiveness thing. a healthy/happy marriage is first. and becomes more support in the long run.
Since your wife is so decorative, I'd show some pics of beautiful tanks which you could create around your chosen stock. why not include her interests rather than alienate your life partner? and include some stock with eye appeal, not only swamp things with fangs. a really nice tank could add more beauty to a room than ANYthing, and with enough compliments, she will be won over.
We've been married for decades & he did NOT start out this supportive of differing interests. :-o
I could share more indepth by pm, if you wish.
Husband is my best friend on earth.
