The smallest Cory catfish is the Corydoras pygmaeus, commonly known as the pygmy Cory. It typically grows to about 1.2 inches (3 cm) in length. These tiny catfish are popular in aquariums for their small size and social behavior, often found in groups, making them ideal for nano tanks. They thrive in well-planted environments with soft substrates.
Only if they are Corydoras catfish, or Cory cats. Those are the best kind of catfish.

I would say like any albino, it is a mutatation of it's species. So if the alibino was bred back to it's parent species which is the bronze cory, you would most likely get mostly natural colored fry.
It depends on what type of cory you go for something like a peppered cory would usually grow no bigger than 8cm

Cory catfish are not completely scaleless, but they do have very small, reduced scales that are often not visible. Instead of scales, their skin is covered in a layer of mucus, which helps protect them in their natural habitat. This lack of prominent scales is characteristic of many catfish species, allowing them to thrive in various aquatic environments.
Adding a Cory catfish to a red-eared slider's tank is generally not advisable. Red-eared sliders are omnivorous and may see smaller fish, including Cory catfish, as potential food. Additionally, the water conditions and habitat needs of these species differ significantly, which could lead to stress or health issues for the catfish. It's best to keep them in separate environments that cater to their specific needs.

A extra large Green Cory Catfish can be as big as 1 to 1.5 inches from tip of mouth to tip of the tail fin. They are non-egressive and their mouths are small so unless you are keeping them in a tank you are raising fry, then all should be ok.
i think 1 or 2 cm
As long as the tank water is clean, and the fish are being fed properly, the catfish may just be entertaining itself by swimming that way.
