I have a twenty gallon and a five and a half gallon. Both are heavily planted tanks with a bunch of filtration. The tanks are heavily stocked with small freshwater fish and inverts.
Get the biggest tank you can, test water parameters and change water. If you get more fish, get more plants and filtration.

When you see signs of stress in your fish, you can then take steps to identify the source of that stress and then to resolve it before it becomes a major issue.
Keeping your tank clean is about more than just aesthetics - it also affects your fish.
Catfish are an extremely diverse group of fishes and many of them fare well in the home aquarium.
