such a small tank?

I saw this tank pic online.. how can a clown fish survive in such a small tank?

Quit well, short term, if all the parameters are kept in check.
I wouldn't recommend this kind of tank for 99% of reefers, but I have seen some absolutely stunning reefs in as little as a gallon of water

hm i wonder how they filter things, manage toxic wastes etc. i guess they will have to change water very often

100% water changes daily is the usual MO
