Most of the people on here will not be thinking that. We were all beginners at one point in time and we all go through the same mistakes. The more seasoned fish keepers try to steer people in the right direction so you don't make the same mistakes we did. The fact you came here asking for help, shows you care about your fish
When it comes to feeding fish, if in doubt, feed less. Fish don't need as much food as people or other land animals and if there is food left over in the morning, try feeding once every second day.
Make sure you have some driftwood and algae for the suckermouth catfish. They need it to help their digestion.
