I have a striped raphael cat, and it is not one that really adds to the enjoyment of fish in your tank.....you will never see it unless you have night lighting....When the room is lit, ot when your normal tank lights are on, this fish stays hidden.....
None of your tanks are larg enough. This fish grows to almost 9 inches, and the minimum tank size is 29 gallons....it is better in a large tank that has lots of caves/ hiding places.
It is peaceful and won't bother other fish.
A good site to visit is...

Hope this helps.
