I trieed to get a better shot of this. The fish was fine yeasterday and then this morning it had what looks like a growth on its side. Its been swimming as if it cant use its tail. Of note, it slept on the rocks last night. It usually sleeps on the glass. I am working on my algae problem. SG 1.024, ph 8.02, ammonia 0, nitrates 10, phos 0.4

Got the worst of a fight?
Looks beaten up to me.
Ok at night, dead in morning, I lean towards disagreement.

Looks like it is the victim of aggression (there could be other issues at play). What is the stocking?

uzz but may be a victim of aggression and needs to be isolated
Normally fish can heal after damage but I recommend quarantine and treatment with seachem neoplex otherwise kanaplex and even stress coat to restore body slime

Looks like aggression to me as well - round bite mark on its side and some missing rays on the caudal fin. Some blennies can be pretty nasty.
