hello people,
I need help, there are about 3 weeks with my first paycheck I bought 2 L'46

. They have about 3 cm, and i never saw them eating, although they are not skinny or anything, i give them food before the lights go out, but I'm always wondering if they will eat or not .. .. now I'm give them Artemia, shrimp, zucchini, bloodworms, pellets, and mussels .. is something wrong in the food I give them? Some tips to improve?
The aquarium has many hiding places, but no substrate, I was thinking put Ada Amazon I, or sand, which is best for them?
At the end of the month I will buy a camera and shot some pictures.
Greetings to all
Sorry for my english
