I suggest you not to use gravel, because it may cause damage to these cl's mouth as they search for food on the bottom, I recommand using round small soil, this kind of substrate can be easily removed, convinient, and a bit cheaper than gravel. moreover, you can put gravel on the bottom, then 1 kg ADA above, and small ground soil on the top. this will give you the "good" microganism system, nutrition for the plants and moss, but still protect you fish.
p/s: is that Anubias Congo that you tied on the wood, the wood looks perfect when the cl's rest on it.
