According to this page... http://www.aquarium-pond-answers.com...-silicone.html
...it seems as though, if there was even the tiniest way for oil to get "under" the sealant, it would work its way in and cause the silicone to come off the surface. Also, it sounds like the silicone was bound to fail eventually as apparently it doesn't adhere very well to acrylic or other plastics (I only have glass tanks so I didn't know about this). So, it looks like you'll need to use some sort of sealant other than silicone. As for what to use...beats me!
As for the white clouds, they are fairly hardy fish. However, when you hear people talk about "starter fish" what they're usually talking about is the ability of that species to survive the ammonia and nitrite poisoning that the fish must go through if you cycle with fish in the tank. Because many (probably most) new aquarists don't read about the aquarium cycle before starting, they're unaware of the cycle so think it's necessary to start with these "starter fish." However, if you do a fishless cycle or have a heavily planted tank, you should be able to stock all but the most finicky of species once the cycle is complete. White clouds also aren't quite as active swimmers as danios, which swim around at high speed pretty much all the time and therefore need a fair bit of swimming room. White clouds do better in smaller spaces.
