so have questions building up all the time I hope you don't mind. With the plants again do you find you stay clear of certain species and tend to stick to the more Robust ones. Or you choose exactly what you want.
I don't mind questions! Ask however many you have.
I can point you toward some great sites that helped me out also, but I know that when I was researching it helped more to have someone to actually ask questions.
This particular tank has everything needed for high-demand plants, so I get whatever I want for this one. I have had other medium and low tech tanks, plus a high tech cube 12g that's new. I adjust the plants based on what will grow in the particular tank's conditions.
That being said, I had a hard time with a type of hygro that just did not want to grow in my tanks. Mosses are supposed to be easy, but in high light they are algae factories in my experience. Sometimes where you put plants matters too. Some plants actively secrete things that harm other species. You just have to try stuff out and see how it goes.
If you're looking for an easy start, go with Anubius, Java moss, cryptocorynes, Amazon sword, valisneria. You can buy little fertilizer tabs to put in the substrate to feed those plants, and they'll do well under a marine land double bright LED, or high output fluorescents. Maybe even regular fluoro bulbs. I also recommend Flourish Excel to give them some carbon to work with. You won't get amazing growth with this, but you can easily green up a tank.
I had a small Anubius in a Betta tank with a small low-light LED clip on light. It grew slowly but happily with almost no input from me. I think I put in a small amount of liquid fertilizer when I did water changes. Flourish bottled.
Anyway, you can do it! Start small and easy and work your way up.
