It is so rich and variable underwater world and you are right that part of nature hidden from human's eye thank such aquariums we can enjoy the beauty of not well known types of plants and animals.
I love to visit underwater aquarium the whole atmosphere is different, it is normally dark and when you walk through corridors instead of walls you have a huge and tall glass wall that is separating you from that world.
You have captures the beauty of that mysterious world very well.
thanks
you should go
or have one small aquarium at home
that's also possible :)
I'd rather not though
I really am bad at taking care of pets
unless they're guinea pigs, chickens and quails then it's alright
or a butterfly - I can do that
