You should look at remineralising the rainwater if you want to persist with that. Unless there is an issue with your tapwater, you would be better using that.
I can't agree with anything what you say. Rainwater is the best for plants and much better than tap water. Tap water contains loads of chemicals. Mate, distilled water is something different than you think! Maybe I will need to reduce amount of fish.
Anyway. My question was if those species are ok to live together. Do they need similar water spec.?
