I would get any type of stem plant-they are usually sold in bunches of 6-10 stems, lots to pick from, sword and marimo balls will not be enough to make a soil based tank fish safe
Here is a link for you to look at some stem plants and to get names of what appeals to you...okay it won't let me post a link..so google sweet aquatics or any aquatic plant site and look at the plants and read more about them
Remember you need at least 80+% of the floor planted in stem plants with soil based tanks to start, some can be removed later as the tank matures.
No, you don't need CO2
Yes, stem plants that you plant in the soil
the stem plant is what will halp make the water safe for the fish while the soil is starting its emersed life, it can get toxic during this time and you will need to make daily to weekly water changes until the soil is stable and the stem plants start to actively grow and this can take a week for the plants to start to actively grow and 1-2 months for the soil to start its emersed life.
Once planted and the water clears it is safe to add the fish as long as you make the needed water changes until the tank is stable.
thanks do you mean have many stem plants in? i was looking on theplanted tank website and whats co2 and do i need it? i was planning to plant the tank and add the fish straight away because the fish was all ready living in the tank before i wasnted to plant it.
Your welcome weluvbettas, the bulb sounds fine, make sure you have plenty of stem plants in the soil based tank before you put any fish in it and monitor the water and the fish itself for changes.
It is hard to say if the plants are safe or not without know what kind they are, but most are safe IME-rinse well before use.
