crippled valentini puffer

[reefnut]

woke up this morning to find my valentini in one of my mj 1200's.was cleaning them last night and stupid me forgot to put one of the covers back on it.any ways i dont know how long he was in it could have been 11 hours at most.his tale end was sucked in.i think its broken and or paralyzed.some of his skin is torn and his tail is red like a cooked lobster.he is still mobile with his other fins but he just wedges himself in the rock.not sure if i should just flush him now or see if he pulls through.
