Well i wont dwell on the fact that the chosen fish arnt suited to such a small tank.
With a planted tank, the plants can only grow to the weakest link in the chain. The main parts in the chain being, co2, light and food(ferts). With other things impacting growth also like temperature, oxygen ect. And adding more of one thing without another wont push plant growth much further.
Kool little tank though, if abit on the small side.
Planted tanks come in different grades from low tech to high and inbetween. Mainly Light capabilities, co2 concentration and ferts donate this.
Dont get me wrong adding ferts to a tank with low light without co2 will give benifits when used in moderation but is limited.
