Well, first one of your friends has to find one. If they find one and then publish it to their page, when you see it in the bottom right hand corner there will be a button that says "adopt the squid!" When you see it, click on it. It will then take you to your Happy Aquarium page and should say something like, "YaY! You gave the Squid a home!" or, if someone has beaten you to it, (sorry) but it will tell you that it has already been adopted. :D

You can't buy a female squid. You must save one. An orphan notification will pop up sometimes when you go to your aquarium asking if you want to save an orphan. When this happen post it. and your friends will be able to adopt it. You may not adopt your own. You have to adopt one from a friend.

Probably a baby squid if something did not happen to the water that would hurt the adult or baby squid.

You can only adopt male baby sea turtles and female squids, but if you want the female sea turtle you can buy it for 23 pearls or the male squid for 623 coins. Hope this helps! (Oh and if you were looking for more interesting colors, you can mate the male and female squids and possibly get a hot pink squid or golden, or if you mate the turtles you can get a gold one.)
You can get a purple, blue, hot pink, and golden squid. You can get the golden and hot pink aquid by mating the blue and purple squid.
