To answer ur questions hoppity my frogs r pretty 50/50. Sumtimes theyr in the water, otther times their on top of the foam, the decorations, tthe glass, they get evrywher. Iv had these guys about a year or 2 and i was jus getting bored with the same old look of the tank. Evry tank cleaning i rearranged the decorations, sure but thers only so many rearrangements u can do inside of a 10gal tank. This small build was fun and as far as the "all natural" is concerned, im proceeding one step at a time, eventually id like to get all natural green in ther. That doesnt mean im going to stop using the foam tho. You can literally build geography with foam, thats jus too much fun to pass up lol
