The Axolotl is a Salamander stuck in its larval form. It is a bit of a freak of nature, even in this larval form it breeds and rarely "transforms" into a land-based Salamander. The Axolotl MUST have very cool consistent temperatures, it will suffer in warm water. It is also prone to having it's long external gills nipped by fish and is therefore best kept in species tanks. It will also try and eat anything it can fit in its mouth, including invertebrates, fish and other Axolotls! This could also include their substrate so they are best kept on large river rocks, too large to be eaten, or shallow sand no deeper than 2.5cm (1"). They are very messy and will require a very well filtered, but without strong current, and fully cycled tank. They don't require a deep tank, at least the length of their body in depth should be fine, they will often just perch near the surface, not being overly active animals except at feeding time. They also do not require very heavily oxygenated water, indeed if it's too oxygenated their gills will shrink and wither! Read our article linked above for more details on these creatures.

Sure, it’s nice to watch fish float around in their tanks, but there’s never been anything quite as mesmerizing as watching a jellyfish float through the water. Their movements are graceful, and they’re extremely fragile, which is exactly why it’s not easy to just toss them in a tank with other sea creatures.

Kocak is no novice when it comes to aquariums. He’s kept fish since he was a toddler, worked for an aquarium shop for a spell, and is now internet-famous for his drawings of , cuttlefish and other tank-creatures he keeps. (He’s also a freelance artist who has created more than 250 avatars for the scientists of Twitter.) Baffled by the fish’s quick demise, he went back to the aquarium shop to see if they had any theories.
