Clown loaches are a little bit more outgoing then some other types of loach. Even then they can be elusive. They stay near the bottom of the tank and often hide behind plants. Due to their bright orange coloration they are still easy to spot. Their relative the Kuhli loach is longer and more eel like. They are much more prone to hiding as you described.
Clown Loach (Chromobotia macracanthus) grows to be quite a large fish (10 inches to 12 inches long) and they should be kept in groups of no less than 5 fish. They will mix well with other peacfull but largish fish like Silver dollars and Bala sharks. The minimum sized tank recommended for these larger species is at least 6 foot long.
That's not a good idea at all. The Malawi cichlid will be far more aggressive than other of the other fish and will bully and beat them literally to death. Since both the Malawi and the clown loach like to live at the bottom of the tank and the Malawi will claim a large part of the bottom as his territory, this will lead to guaranteed problems for the poor clown loach.

You have really small snails in your fish tank and they are killing all your fish does anyone know how to get rid of them or why and how they got there?
Unfortunately there isn't any clown fish (Nemo) look alike that exists. The closest you may get with something stripey that is fresh water (but they are black & orange) would be a clown loach, but they need very large tanks (at least a 75 gallon) as they grow pretty big, and they are a more advanced hobbyist fish.
