Sounds like a good start.

In breeder tanks, I have always been a huge fan of 18" to 20" tall. Gives some height, without being too much, for fish to swim and head room for aquascaping. Every 40 I have set up was great for a while, but then always wished I had a little more height to expand a little. Anything over 22" ended up just looking too tall.

Looking forward to seeing this one come together.
