Just because you have an aquarium doesn't mean your pet options are limited to fish. There are plenty of interesting aquatic and semi-aquatic critters you can keep in your tank that are a little off the beaten path. If you're looking for some alternative aquarium pets, we have 10 non-fish suggestions for you.
RED-EARED SLIDER TURTLE
Turtles are among the most popular pets, but there are many different kinds, and they require different habitats. The most popular aquatic/semi-aquatic pet turtle is the red-eared slider, which also has the distinction of being the turtle species whose name sounds the most like a skateboarding trick. They’re not overly difficult to care for, but their aquarium
will require vigilant maintenance. Red-eared sliders are semi-aquatic, so while most of the tank should contain frequently changed, fresh, clean water, you will also need to provide a “basking” area for the turtle to warm itself under a heat lamp. (Petco)
