Blue ramshorn snail advice needed!

[kaiden]

I have a 29 gal tank setted up recently with sand gravel called Nature's Oceans premium marine substrates. This is what i'm running: Emperor 400 filter, sunsun JP-022 powerhead, good-enough heater and an extra duel air pump with an air strip to cut algae growth. The only fish i have in there is a dwarf gourami and a goldfish look-alike fish with a black spot by the end of it's tail. ok so i've done quite a few article researches but can't seem to find exactly what i'm craving to find out. i just ordered online: some live plants and 25 malaysian trumpet snails to clean up my gravel. I might get me some blue ramshorn snails too.

What i want to know is...
-does the blue ramshorn's population increases dramatically like its cousin red ramshorn?
-how fast in days or weeks does it take for the blue rams to reproduce and do they reproduce in massive numbers?
-do i need to add calcium tablets, drops or bone/egg shells to help the hardness growth for the snails since i have natural coral/seashell gravel?
-will my dwarf gourami take bites or bother my malaysian trumpet snails + blue rams?
-how fast will 25 malaysian trumpet snail reproduce and will they pesticide my 29 gal in 6 months? (i don't want to really get assasins for the malaysians since i want to get as much rams as possible)

I really need these answers, yeap every one of them will help and advices from D experienced ones if you may. THANK YOU!!!!!!!!!

You will have blue ramshorn snails coming out of your ears in a month. I have them by accident, those and pinks, reds and albino ramshorns.
