I had fish for a while, but they were actually to feed my turtles...
I love turtles, tortoises and terrapins of all kinds. I have kept soft shell turtles, red eared sliders, painted turtles, snappers, maps, muds... you name it, I've had it at one point or another.
Soft Shell

Red Eared Slider

Map turtle

Mud turtle

Snapper

African Spur Thigh

Painted turtle

And I have a fascination with sea turtles as well. like these guys:
Ridley turtle

Loggerhead

Not to mention the giant tortoises from the Galapagos, like the Saddlebacks...

and the regular, run of the mill Giant Tortoise...

Of course, while I've actually
ridden giant tortoises, I have never kept many of these varieties at home for obvious reasons!
But, these are the kinds of things I have always kept in my aquariums. I had fish when I was a kid, but they never really fascinated me as much as turtles do. I always dreamed of a 1,000 gallon marine tank with a small shark in it though, like a white tipped reef shark, tiger shark or even a nurse shark. Whoey and I planned to set one up years ago, but never did. Someday maybe...
