QT and Fallow Period My Journey

[josephxsxn]

Well I almost cooked my fish!! I did a waterchange and never put the probe back into the tank (it was going through a lid I had to remove to change the water.) It was just warm enough that the cold alarm didnt go off, when I managed to notice (tank was warm) it was up to 92F !!!!!

Luckly! everyone is alive and still well. I am wondering if this limited heat wave changes when I need to dose my Prazi again? This calculator seems to imply that if I had it that high for 5 days I would dose again on day 6 not day 7. But now that temperatures have returned to normal in QT (80.5f, 26.666c) will I be fine just waiting for the 7th day as planned?

Fish still doing well in the hospital but my display tank seems to be developing dinos. Some searching around on the forums shows this seems to happen if your nutrient levels get to low. Will have to try increasing feeding the display tank to boost levels again during this period.

Spent some time observing the fish today to see if anything questionable seemed left. Two concerns 1) Powder Brown has a blemish which I am unsure what it may be and 2) sailfin tang looks beatup around its face, in sunlight appears to be some red dots. Other Chromis appear to also be beatup around thier eyes and faces too but unsure of color

Sorry about the salt on the glass on the one sailfin photo.

I have already done my second round of Prazi. Any thoughts on if I should do anything more @Jay Hemdal .. don't really like the idea but was considering a freshwater dip for the Powder Brown but would be open to any other idea.

It looks to me that the sailfin has the start of some HLLE. I can’t see the PBT clearly, but it doesn’t look like a serious lesion to me.

Thanks Jay I was concerned the PBT mark may have been some type of fabeled Prazi resistant fluke, but I just found another post by you talking about the lack of evidence around this. I'll make sure to keep up on a more varied diet for the tangs.

So watched some more today one of the Chromis still has long stringy white poop with clumps. It's only been 3/4 days from the second Prazi dose. Wondering if I should give it more time, perhaps a 3rd dose or look at something like Fenbendazole as an alternative dewormer to try.

 

[Jay Hemdal]

The PBT mark bears watching, mostly to see if new ones show up. The stringy poop in the chromis can be: 1) just mucus from unknown reasons 2) bacterial infection 3) Hexamita gut protozoans 4) internal worms. Without looking at it under a microscope, we can’t really say which it is. Based on the metro and prazi treatments the fish have had, you can probably rule out 3 and 4.
I’m not a big fan of fenbendazole in water, have seen some serious toxicity issues. Properly dosed in food seems safer (I posted an article on med foods here).
Prazi treatments do fail, but there is no evidence of actual genetic resistance: what happens is: some flukes require a 4mg/l dose to kill them, the eggs of some flukes are not killed, and most importantly- in tanks that have had multiple prazi treatments, bacteria grows that consumes prazi, fast enough to cause treatments to fail.

I managed to snap a few more photos in better focus of the powder browns side with the black mark..

 

[Jay Hemdal]

Thanks, in looking at these new pics, I’m just seeing a minor bump/scrape. I can see two parallel lines. If it were my fish, I would just watch it for any other changes. I’m not sure what you should do about the chromis though, that’s an unrelated issue.

Looking some more today both have what ill describe as a swollen anus which seems sticking out in addition to their white stringiness. Neither seemed to interested in frozen food today when getting fed.

Lack of a feeding response is a very serious symptom, and it means that medicated food is off the table as a treatment.
I scrolled back some, but didn’t see it, have you dosed these fish with metronidazole? General Cure is that plus prazi. Metro can help for gut protozoans.

[josephxsxn]

Yes I did a 3 week metronidazole (Metroplex from seachem) treatment in the water column. I plan to do a waterchange tonight just to help improve any possible aspects of water quality that can be done. While it may not help here I did put in an order for a microscope, we will see if it gets here in time to be of any assistance.

Well as of late night one Chromis ate and the other did not. This morning one of them clearly has a very swollen belly almost pinkish under tones. Comparing the two one has a very flat body line and the other is swollen and pudgy. I am guessing a fatality is going to occur soon. To bad this is the pair that breed in my frag tank on thier own . @Jay Hemdal any thoughts? C

Photos are of the swollen Chromis, except for the photo with both.

Could that be an egg bound female?

Maybe, but kinda blows my mind that they would breed in this tank. Reading more had me thinking that maybe it was a secondary infection from purging the worms with Prazi and to maybe pull them both out and treat in a smaller tank with KanaPlex (Kanamycin.)

If it was an egg bound female is there anything that can be done to save her?

Well, what took me down that road was that you said these fish were spawning in your frag tank. When you moved them, they would stop spawning, but the female is still going to produce eggs, they just don’t get released...this causes dystocia, egg binding. It could also be an infection, but unreleased eggs often become a site for infection, so it all may relate...no treatment for this on small fish tho.

Not sure what has changed but the bloating is no longer present and both Chromis ate tonight

Exciting end of year, only 3 more days until my extended fallow period is done! I am wondering if I should stage the fish and not put them all in at once, so the ammonia load isn't to crazy and the tank has alittle bit of time to build up it's biofilter. Am currently thinking 2 phases non-tangs and then tangs. Then maybe wait a few days or week and put the second phase of fish in. For what it's worth I have been feeding my display tank abit very lightly to keep the inverts alive and well.

Should I stage them and not do them all at once? Is there anything else I should be considering?

Non-Tang (phase1)
2x Orange Line Chromis
6x PJ Cardinals
1x Foxface

Tangs (phase2)
1x Scopas
1x Powdered Brown
1x Yellow Eyed Khole
1x Sailfin
1x Naso

As of today all the fish have been moved back into the display tank! So far everyone is eating and swimming around well, to my surprise the Chromis are actually being bossy to the newly incoming tangs. I found a mark on the Naso tang I didnt notice in QT that I would guess is a whiteish bacterial infection, it shows up really easily in the blue display tank light. For how I am just going to keep feeding, if it starts going wrong will probably trap the Naso and treat with something like Cipro.

Big shout out to @Jay Hemdal for consulting and offering advice along the way. It really made me feel like I was taking my hobby to the next level getting advice from an expert such as yourself. Happy New year Jay may 2021 be great to you!

Could the naso just have gotten scraped up during the transfer? That happens pretty often when moving fish and usually doesn’t require treatment.

@Jay Hemdal Very possible I used nets, one tang got its fin snagged some.. I didnt ask if it was required but I caught them in the 'copper' net (only used in qt tank), flipped them to a clean net, washed them with display tank water and popped them in to try and transfer as little copper as possible. I'll give it some time and observe the Naso before I do anything.
