For a 160 gallon 10 snails is a fraction of what you will want.

I have a 25 gallon, 20 gallons of actual display area and I have 5 super nassarius, a half dozen or so trochus, astrea, and nerite and now hundreds (literally) of stomatella. They all have plenty to eat and algae still grows on the glass.

I also have two hermits.

Just don’t add them right at the beginning. Add them after you have some algae growth and in stages.
I have 25 turban snails in a 420 and some have died off due to no algae being available. 10 turbo snails do a lot of work they are large and work all night eating algae. Also a tomini or bristletooth tang can be added if they aren't keeping up but I doubt that would be that case. Turbo snails are larger than any of those snails and almost exclusively feed on algae.

It doesn't make sense to add a ton if they're not necessary. Add 10 turbo snails and a couple hermits to scavenge and add more later if needed, but they are efficient at what they do.

For sure, snail type is important. For the types the OP listed he’d need way more.

As mentioned, reefcleaners.org is a good resource. Even if they don’t ship to Bangladesh you can see what they recommend.

155 gallon tank:
170 nassarius
29 cerith
46 astrea
42 hermits

Of course this is not right away in a new tank.
Yeah, have to wait for the tank to have algae and then add as needed!

I will have 3-4 tangs and maybe a fox face. So, do you think that 6 trochus snails will be too many? I am thinking of getting 6 trochus’s for algae, a conch for the sand bed (not sure what type yet) and a cleaner and fire red shrimp to scavenge for stuff.

Tangs and foxface will definitely be great algae cleaners. Shrimp depends on what livestock you plan on adding, would be a no go if you want triggers or wrasse. 1 fighting conch would be enough for a 160 I have only a fighting conch and tiger conch in my 420 predator tank.

I'm not familiar with trochus and how efficient they are. I'd think 6 would be okay though.

I see thank you so much! Which conch do you prefer and why? Please let me know!
