Blenny breathing heavy

[SwimLittleFishy]

I have a new 40 gal salt and am new to hobby. Have had fresh tropical for years and I understand ammonia cycle. I have had this lawnmower blenny for a week. He is breathing heavy and doesnt move around much. He moves from nook to nook. Nori is available. Water tests good. 5 fish in tank now. I started adding fish in Mid february. 2 clowns, 1 damsel and kole tang.

Did you QT him? If not, it's possible he has parasites or worms inside of his gills.

My starry blenny always breathes heavy. I've had him for 5 years now. I'm thinking it might be due to old age but then again it might just be an algae blenny thing.

He died within hours. The water tests ok. Bummer
