Thank you all so much!!! Your compliments mean a lot to me! I'm not sure on the future occupants.
I have 3 danios in holding, 1false julii corry and 1 emerald green "cory" all schooling, so I have to fill them in 1st. I'm not nuts about danios but perhaps in a larger group they won't be so nippy. So, I might have room for 1-3 other fish.
One constraint is water pH 8-8.2. The pH stabilizers that I've looked at say no plants. And, it's best for me to just pick a fish that goes with local water chemistry. Should I get sick, the kids would be too confused.
However, now adding CO2 my water pH should change somewhat. Same with after I add the driftwood. ( one piece has been soaking about 3+ months and both boiled daily for 3 weeks )
