Popeye Update

Just a quick update as I’ve simply not had time to take pictures, nor get the permissions I’ve asked for.  In a nutshell, once again, we *may* have adverted a crisis.  I’ve been consulting a fish vet for the past few days, and for lack of a better way of explaining it, there are lots of things a vet would want to do to a fish in this condition that aren’t practical.  Not practical in so much as the vet I’ve been talking with is 3 hours away, and can’t be here on site to see the fish even if I could afford to compensate the vet for the trip and time combined.  The other practical issue is one of risk and probabilities; netting a fish with an infected eye is never a good idea, and as I learned, a swab of the eye would likely yield no pathogens anyways as the causative agent is probably largely internal.  Plus, if there is an ongoing infection of the eye itself, I could easily see a swab somehow popping the eye and well, making matters worse.  In the end, it is my opinion that while consulting with a vet made for a very good sounding board and gave me some new things to consider, without the direct interaction, there was little if anything different the vet would’ve had me do.  Plus, considering I was seeing some improvements as we were consulting, it’s difficult for any doctor to suggest a change if what’s being done outwardly appears to be working.  I get that, 100%.  And on the topic of prevention – minimize stress, maximize good water quality. No surprise, I’ve been doing that for years.  So I think none of us have even a guess as to why this is happening, which means that every hypothesis we’ve put forth could be valid.

So yesterday (Tuesday) was the last dose in the 5 day course of Maracyn and Maracyn II, which I ran only weeks prior for the mouth rot.  I’ve been feeding the Dr. G’s food daily; I’ve made this judgement call to feed at twice the package’s recommendation based on several things, but perhaps most importantly that the Lightning Maroon isn’t an aggressive feeder (never really has been) and thus, it’s difficult to get this fish to eat as much as  you might think it should within a 1-minute time window (as prescribed by the food’s directions).  Still, it’s important to note that this food introduces both Metronidozole and Kanamycin to the mix, and it is again reef safe as far as I can tell.

The downside here is that the Lightning Maroon’s interest in food was diminished today, so getting a fish to eat the medicated food is obviously a problem.  The pair however, has been cleaning like crazy…for all I know the pair could wind up spawning (my female Percula often has a diminished appetite in the day or tow prior to a spawn).

The actual eye – much improved and it would seem that there isn’t any vision loss.  There is still some tissue bulging out around the eye however, which made me reluctant to stop the treatment with Erythromycin and Monocycline (active ingredients of Maracyn and Maracyn II).  I’m trusting the vet on this one.

Here’s the real worry, and sadly this does make some sense.  Mycobacteriosus.  Both the female Maroon I first had so many problems with, and then the Morse-Code Maroon, basically shared similar afflictions (pop eye and mouth rot respectively) that I have encountered in none of my other marine fish.  Yes, that’s it.  NEVER.  I cannot recall ever having popeye in another marine fish here, and certainly not mouth rot.  So why would 3 out of 6 PNG Maroons be the only fish in my entire household to ever wind up with these diseases?  Well, it’s much more understandable if we view this as a pathogen that they were all exposed to before they came to me.  We know that Mycobacterium can lay dormant in fish for a long time, which could also explain why the Lightning Maroon has gone this long without issues.  If it IS Mycobacterium behind the external and recurring symptoms I’m seeing, well, that could be *it* for the Lightning Maroon no matter what I do.  It’s a very harsh theory to even consider, and even more alarming given that the theory happens to explain a whole heck of a lot of the issues I’d had, let alone also possibly explaining why these problems are isolated to a small group of fish from one species from one location, where half of them have had semi-common symptoms.

For now, please just send all those positive vibes.  The tank got a 10 gallon water change today, and hopefully the Lightning Maroon remains on the road to recovery.  Let’s get several more good years with her if we can.

I believe I shot these Sunday AM.

 

It is now Monday AM, and honestly, things are improving.  The appetite of the Lightning Maroon remains strong, which I’ve used to ensure that it continues to feed on the Dr. G’s antibacterial formula.  I should preface this by saying that the Lightning Maroon has always been a timid feeder, so food generally has to flow right by its face / into its territory for it to feed.  So I’m definitely not following the Dr. G. feeding protocol (as much as they can eat in one minute, every other day).

In talking with the man behind Dr. G’s feeds, the feeds are set up to roughly deliver a “minimum effective dose”.  In the case of the anti-parasite Dr. G. formulation (which is laced with Chloroquin Posphate), you can quadruple the feeding regime (twice per day vs. once every other day) and have no ill-effects on the fish (although the Dr. doesn’t recommend that).  Knowing how most every antibiotic is normally delivered, it honestly doesn’t make sense to dose every-other day via feed, so I’m going to feed the food once per day to maintain antibiotic levels.  It’s worth mentioning that the active ingredients in the Dr. G formula are Kanamycin and Metronidozole.

All in all, this means that I have no less than 4 antibiotics running around.  I’ve been talking with two fish vets who I’ll refrain from naming for the time being.  One has of course, expressed concern over the “shotgun” approach, understandably so.  For me, I’m thinking that the repeat of the Maracyn & Maracyn II are probably of little efficacy, but they were what I had on hand to immediately address the problem.  Still, I am more likely to credit the Dr. G’s as the moment, if only because positive progress only started being made once it was introduced to the regime starting on Saturday evening.  Still, it could be the other medications.

The main goal here is twofold – #1. effectively cure this latest round of garbage.  #2. figure out WHY it’s happening soas to prevent it.  As of Monday AM, the eye looks better (less white stuff), so maybe we will get through this latest bout again.  But I’m fully wondering what the heck is causing the fish to break down repeatedly.  Mechanical damage? Food?

Or could we even be looking at an old-age, immuno-compromized fish?  Afterall, they DON’T live forever, they are NOT immortal.  Could it simply be that the Lightning Maroon is an older fish, nearing it’s time, and all my drastic measures are simply staving off the inevitable?  I hope not.

Despite all this, the male is cleaning the tile like crazy.
