Bichirs are too big. I started looking at loaches and they had the same look and were way smaller, pretty hardy and bottom feeders to help keep the tank clean. I saw that I would need a better filter with this species because they burrow and mix the substrate around. So I like the Kuhli loach and the red tailed shark. What do you think? What other fish can be used if the tank was 40 to 50 g?

Okay good to rule that out. Loaches are a really good choice and kuhlis are super easy to keep. You don't need a softer substrate if you provide a lot of hiding places. And kuhlis do best in groups of 5 or more. As for the red tail they are a litter more agressive than rainbow sharks which have the same look so I'd go for the rainbow.
