Hi all,

This is my first post so apologies if it is missing any information, let me know if it needs more and I can try to provide it. My tank has been going for about 4 months now. Early on, I had added two clownfish that were doing great. A month or so later added a yellow watchman goby and tiger shrimp (paired, both are pretty tiny). And around 3 weeks after that added a swissguard basslet. Everything was going great in the tank, until around 3 weeks after I added the swissguard I noticed some odd behavior.

The swissguard had some labored breathing and was no longer interested in food (prior to this, he was growing more and more comfortable in the tank and was eating well). I then noticed he had white stringy poop. No other symptoms and no visible spots or parasites. We treated the tank with prazipro under the assumption it was an internal parasite. The swissguard hung on for 4 days before he died. He had increasingly labored breathing, and in the last two days his tail began to fray. This may have been due to the clownfish bugging him at the end, though we never saw them go after him at all.

I kept a close eye on my tank after this and all the other fish had been eating fine and showed no signs of illness. Today I woke up and checked the tank and my 2 clownfish were dead, with some white slime on them and some tail/fin fraying. I know this could potentially be brooklynella, but I guess I am at a loss considering the swissguard's death ~5 days prior. It seems like it would have been related to that illness, but it killed the clowns much quicker before I even had time to notice anything was wrong.

The watchman goby is still alive and looks healthy, and is eating.

The only change in the tank prior to the first fish getting sick was the addition of two corals: green star polyps and clove polyps. Both were dipped in CoralRx before adding them to the tank. I also added a single trochus snail at that time. Corals and snail are doing just fine.

My best guess at this point is a bacterial infection, and we did treat the tank this morning with melafix. How likely is it that this was two different diseases? Any suggestions moving forward? For now, I am going to keep an eye on the remaining livestock and wait a few weeks before adding anything new.

Salinity: 1.024

Starting with basic questions:
How old is the tank
What test kits are you using ?
Did clowns show heavy breathing, refusing to eat, hazy coloration ?

How were fish acclimated /introduced to tank and for how long ?

Melafix wont do much as it is a tonic and utilized teak tree oil.

Glad to hear some are alive and functioning as they will be an indicator of tank health for the next several weeks. Monitor and maintain water quality.
Any pics provided always helps

The tank is about 4 months old, and the tests were run using salifert kits. Salinity was read using a refractometer.

I was only able to glance at my tank a few times yesterday prior to finding them this morning, I did not see any apparent issues in that time so whatever killed the clowns acted quickly. I am unsure if they had any trouble breathing, but they ate normally ~48 hours prior to finding them dead. Really the only information we have on them is the white slime and tail/fin decay observed after their death. I never saw the white stringy poop the swissguard had on any of the other fish in the tank.

The fish were all acclimated first by floating them for temperature acclimation, then by slowly adding in my tanks water/removing the water they came in over a ~45 minute period. The clowns had been in the tank for around 3 months before death. The swissguard had been in for about three weeks.

Welcome to Reef2Reef!

It is unlikely to be a bacterial infection - those rarely spread from fish to fish and when you do see them, they are almost always related to some physical damage to the fish.

Can't really say what happened here, but given the goby is still alive (and is still eating) it probably wasn't velvet, more likely Brooklynella. Flukes are common in swissguards, but wouldn't have killed the clowns so fast like that.

Melafix - I'm not a fan, it is just a botanical extract, not a true medication.

At this point, my best advice would be to ride things out for 2 weeks just to ensure the goby doesn't contract what is going on, and then consider stocking the tank with quarantined fish going forward - either purchase them online, or quarantine them yourself.

till alive (and is still eating) it
Thank you! The melafix was already added, though this information is good to have. We will probably not medicate with anything else, but maybe a water change is a wise choice. Otherwise, I think we are probably going to do exactly what you recommend, ride it out a few weeks and see what happens.

Is it possible something came in on the corals? I have a hard time thinking it was related especially since they were dipped first. Also just so confusing since the swissguard got sick first and held on so much longer than the clowns. Not knowing is certainly the most frustrating thing here for sure...

It's rare, but not unknown for corals to bring disease into a tank. Here is an essay I wrote on the topic:
