Is this blaso actually an acan?

I saw a fluorescent circle on the $15 frag rack and the worker said it was a blasto. I googled pictures and I can't find a blasto that looks like it. I saw an acan with the same pattern. Did the employee mislabel it? I can't tell the difference between acans and blastos.

Looks like an acan to me, I’ve had them with those bumps before

Definitely an acan.

I heard some acans change color depending on light. Should I aim for low light or medium light in my tank.
