I have this lawnmower blenny in a ten gallon QT tank. Previously had a yellow wrasse in the same tank with it that died about a week ago. Neither fish were very visible in the tank as I have some hiding spots and sand to keep the fish from being stressed. Unfortunately, I didn’t really do a lot of testing at that time as I’ve not had much luck keeping wrasses - they seem pretty sensitive to stress and I’ve lost a few within the first week after I receive them, I assumed this time to be the same... I did a large water change after finding it but didn’t test parameters other than to say my salinity of 1.020 and temp of 77 were the same then as today.
I did a large water change today, stirring up the sand and the blenny came out of hiding. I noticed this discoloration on it, which appears bacterial to me, and so I treated the tank with furan 2 and kanamycin.
I did treat the tank with general cure at first and 2 days later. I have a cycled sponge filter in the tank with them and feed a mix of frozen food and nori as well as putting green hair algae in the tank from my display tank.
I now regret keeping them in the same tank and making it so hard for myself to keep an eye on them....
Anyway, I was hoping someone had some ideas of what this is and if I can do anything else for my blenny.
I do have a seachem ammonia badge in the tank and it is yellow.
