A paludarium project

[cowlat]

got my cp last week. some seeds coming soon. getting more media this friday.

now some idea came up to me to build a paludarium. but i'm kind of a little too ambitious though i'm doing aquascaping too, so i do have aqua plants and fishes and shrimps too.

so...lets get to the point. i wanted to build a paludarium that combines half land half water. the water part will house fishes, shrimps and aquatic plants. land area will house cp and ferns maybe. layout will be like the image below.

my question here is......is it ok for the water with the fishes dampen the sphagnum moss for the cp? as the water might contain minerals as the fish waste will be some sort of fertilizer, if you get me.
a filter will be fixed for the water column too, for cleaning the water.
basically it is combining a aquarium with a terarium.

please give me feedback and advise on this. will it work? will the water cause the cp to die?

thank you
