First fish death :-( - Fire goby

[ThunderWind]

Hey guys
Woke up today to my first incident… Only the firetail was left from the firegoby (Nassarius probably had a party) I cannot understand why. I looked very closely at my fish and didn’t see any signs of Ich or other symptoms of weakness.
I bought the fire goby 1 week and 5 days ago. Very happy with it!
I have a 25-gallon Waterbox AIO aquarium. The tank is 7 months old.

I’ve had 2 clownfish and a cleaner shrimp in it for 3 months. I actively feed them twice a day with frozen krill, mysis, artemia, and AF Marine Mix S. The fire goby ate the same and was active as of yesterday.
It was very happy and decided to add a firefish and an urchin.

• The urchin is happy.
• The CUC is happy (5 Nassarius, 2 Trochus, 3 Astrea).
• Corals are happy (frogspawn and hammer).

I did turn my light up a few days ago (from 30% to 40%).
The sandbed is alive (seeded with copepods multiple times, and when I light it at night, there are lots on the stones and sand).
It was one of those fire gobies that liked to display itself, not hiding much, but it did find a cave to retreat to when it needed to.
It came out very fine with the clowns (who only occupy about 15% of the tank’s volume, always in the corner).

My water values are very stable, and I do 10–15% water changes every week. I dose phytoplankton daily.

• pH: 8.15 (very stable)
• Nitrate (NO3): 7 ppm
• Nitrite (NO2): 0 ppm
• Ammonia/Ammonium (NH3/NH4): 0 ppm
• Phosphate (PO4): 0.03 ppm
• Alkalinity (KH): 9.8 dKH
• Calcium (Ca): 440 ppm
• Magnesium (Mg): 1360 ppm
• Salinity (SG): 1.025

Any takes on the course of death from above information?

Thanks in advance.

Sure, dosent say much i think since CUC enjoyed it, but here you go.

at the LFS it was in a 30 gallon tank with like 80 other firefish (they were really crowded in there)

Any other fish breathing rapidly?

Tail looks like it was nipped. Maybe it was bullied?

Welcome to Reef2Reef

Thanks for the complete post, but nothing really stands out as an issue.

For future reference, and to monitor the remaining clownfish, this short article can you you identify issues:

Yes tail was like that when i got it. First saw it when i got home, and being a freshwater guy i thought for a second it had clamped fins

Looking at the clowns, i actually see some sign of rapid breathing (2-3 gasp each second) comparing to other youtube videos of clowns i do think they gasp more rapidly.

To elevate pH during winter, I run an air stone 24/7 in the back chamber, using an air pump that draws in outside air.

I do see one white spot of one of the clowns just between its eyes but it has always been there.

The rapid breathing could be a sign of gill disease (since it looks like you have any water quality issues under control). I would say anything over 100 gill beats per minute in these fish would be too fast.

Are the clownfish still eating well?

 

[ThunderWind]

Clownfish are eating very well. Active and going after pellets and frozen food. They stay at the bottom half of the tank mostly and there are lots of surface movement from the return pump.

I've just dosed recommended dose of Prime incase of NH3 spike from the dead fire goby.
