Just started FT for windows. Have a couple quick questions...although many were answered elsewhere in thread I didn't see these.

About stuff you buy. The aeration system, temp regulator, cleaning snail and golden seahorse should be in all 3 tanks? Or just tank 1 and 2?

The 4 plants you can buy, same question...all 3 tanks or just tank 1 and 2? And just how well do they work? Are they worth the price?

And finally the 6 ornaments...those are just for the sale tank right? Would have no effect on tanks 1 and 2?

Thanks ahead of time
