My only pet was fish scale not a goldfish
from Game (Ft. Pusha T) – Name Me King Lyrics 1 on Rap Genius
In Pusha’s childhood he didn’t have the opportunity to have a a pet fish like normal kids but instead he brought up coke.

Fishscale cocaine is a refined and comparatively pure form of cocaine.It happens to be a very high-quality cocaine, usually right off the key and uncut. It’s flaky instead of grainy, it’s sparkly instead of dull, and it’s slightly yellow-grey instead of being plain white.
Pusha may also be talking about Fishscale one of the more popular Ghostface Killah albums. He couldn’t have things like pets, but he had music.
