I have a setup like what you are talking about for my TB's, and I have quite a few that are berried right now, and I have a lot of fry in the tank. I use cholla wood, alder cones, bee balls, and Indian almond leaves, Bio-Digest,
Mulberry Leaves, Oak Leaves, stinging needle leaves, etc like you are using.
See my Gallery on my Mr. Aqua 12 Gallon setup. But yes, I think you will succeed with what you want to do.
Use RO Water, 6.4 to 6.8 PH, 0 to 1 KH, 6 GH, 72 degrees temp, 150 TDS, Malaysia Drift wood, and plenty
of places for them to hide out. I also just started using the LowKey Absorption Board. I change my Bio Ball,
Cappa wood, and Bio Digest on the first of each month, and change 15 to 25% of water every two weeks.
I have plants on the right side of the tank, but I don't know if you plan on putting in plants or not.
I wish you Good Luck. I have had to learn some lessons the hard way, but so far, so good on this new
tank setup that I have with a Mr Aqua 12 gallon low iron tank and I made a sliding glass top for it.
