I wanted a scorpion too but ah well they are "dangerous"
Closest thing is the stingray but they are alot of work and too
sensitive
Plus, there seems to be lots of chemicals in our water lately and
the aquarium guy has been complaining that alot of fish die after a
water change now ><
Yabbies are cool too
Get the Zebra ones. They are really cool looking. Solid black with
white stripes!
