My lawnmower blenny has been breathing strangely recently and as of today has started breathing with his mouth open.sometimes the breathing has been fast and other times it’s slow and hard.
Tankmates are a single fire fish goby and a pistol shrimp that were added at the same time with the blenny, there is also 6 hermits and 2 turbo snails but I don’t think they could bother him. He is still eating when I feed, I’ve been feeding PE. Pellets but plan to feed frozen mysis shrimp along with any algae foods I can get for my blenny until algae is growing better in the tank.
The tank is 3 weeks old with the blenny being added after week 1.
When i added the blenny, ammonia and nitrates were at zero and salinity was 1.25 and my tank temp at 78.
Last night I performed my first water change on the tank, it was 20%.
I tested as of 10 minutes ago and the parameters match those I stated earlier when I introduced the blenny as well of a ph of 8.0
In the video and photos you can see the blenny breathing with his mouth open but he has also been pressing up to the glass in a specific corner which I suspect is because a power head pushes against that corner and he likes it? He can easily escape the flow so I do not think it’s overpowered at all. Another thing I noticed that worried me was him laying almost at the top of the water with his body sucking against the overflow but not his face, I noticed that he was not floating and was there by choice but it still worried me, since then I have seen him move there once by choice (he didn’t float to it) . I also have noticed his belly looks a little bloated. I have not noticed any aggression between my blenny and goby in the past two weeks EXCEPT for when writing this post, my firefish is very skittish and my blenny moved up next to him from behind which caused the firefish to strike at the blenny but I did not see aggression go past that.
Could anyone have a possible symptom for his laboured breathing?
