Can you name some aquatic animals that aren't fish that can be reasonably kept as pets? I want the experience of another aquarium but with a different kind of animal...betta fish are really the only fish I'm interested in keeping. I really like long-bodied goldfish, but I don't even want to deal with that much added on to my water bill, lol...
Triops and aquatic hermit crabs! :D It'll sound absolutely horrible of me to say it like this, but triops are an awesome short-term pet to just try out if what I've read about them is true - they typically live about 30-35 days. Only thing is that they reproduce by parthenogenesis if you happen to not get the rare male or female only ones, so it can keep going for quite some time. They just seem way too cute to not try at least once :3
Also, aquatic hermit crabs like I said. I mean. Hermit crabs, but aquatic. How can one not resist? Or even red-claw crabs! Oh, I've been wanting to own some of those for a while ;^; but they seem like they require certain parameters and I can't go looking because them I'll start wanting to plan for those instead of my fish :(
I love my African Clawed Frogs, they're big, and friendly, and horrible beggars! My albino isn't afraid of my hands in the least, and the upside is, if they mistake you for food, their bite isn't painful, just surprising because they're darn fast!! Usually it's 10 gal + for one, larger footprint being much preferred over height (they have to breathe air).
