Fin Rot or Fungus?

Just as we thought the peacefulness over the past few months would have continued, one of our male guppies Golden started to have part of its tail rotting away, leaving reddish marks on those broken parts. It was unlike anything that we have seen before as fin rot usually leaves the tail split open.

Anyway, for the safety of the other male guppies in the main Planted Tank, we have moved Golden to the hospital tank for quarantine and observation.

White spots?

Just when we were glad that our two gouramis are happily together as a pair, we noticed that there were some white spots on the new gourami. To prevent him from passing the virus to the other fishes (especially Nemo since they are of the same species), I quickly set up the hospital tank and brought him over for quarantining.

Anyway, I have decided to name him Vibrant as he has very nice colour on his scales. Hopefully his colour won’t diminish over time in our aquarium.

Upon reaching the isolated hospital tank, Vibrant was of course stressed, unable to understand why he was suddenly captured into another place where he would have no access to other fishes, especially his newly known friend Nemo.

As the hospital tank was placed side to side against the Main Tank intentionally, Vibrant could have a clear view of the fishes in the Main Tank, and vice versa.

In the Main Tank, Nemo soon realised that Vibrant was missing and quickly spotted him through the glass wall. She moved over swiftly, trying to pass through the invisible wall but unfortunately she couldn’t. They were like a couple who was cruelly separated.

Meanwhile, we have not yet decided what medication to put, and decided to observe him a few more days first before we decide what to do next.

Gouramis’ Turn Now…

Just as we are recovering over our loss of the Albino Corydoras (see Another Rested in Peace…), we observed our two Gouramis — Fiesty and Nemo, behaving weirdly too.

210707_fiestyparasite.jpgI have noticed that Fiesty stopped building his bubblenest (and thus no mating between them), and both are having a bloated stomach. Nemo continued to feast on the food given to her, but Fiesty stopped eating totally today and hid himself at one corner of the tank. These are definitely tell-tale signs that they are not being their normal selves and possible health problems.

Noticing long stringy white poop from both of them, I immediately knew they were struck by internal parasites. However, I have yet determined the source of the parasites, whether it came from the dry guppy food pellets, vegetable dry food, or the corydoras pellets.

Meanwhile, I have set up using the largest hospital tank we have (we have three mini-tanks of three sizes) with the filter. Filling the tank with water from both the Main Tank and Guppy Tank, I netted both Gouramis out and placed them in the hospital tank.

I then dropped a little of the Ocean Free Internal Parasite medication into the hospital tank.

Now we will continue to monitor them on their healths, and hope they will recover to their usual selves soon.

Cory’s Update

Here is the latest photo of the sick Albino Corydoras:

He looks a lot paler and has more blood streaks on his body, especially at his facial area.

Cat has dropped a food pellet for him but he did not seem interested and have been in the ‘stoned’ state since then…

Recurring Diseases…

Just when we thought our Albino Corydoras are happily re-united (see Reunions) after one of them contracted Epistylus (see Epistylus and Sick Cory…), the same Cory started showing weird symptoms again.

110707_albinocorysick1.jpgI have noticed a slightly bloated stomach, popping eyes (not sure) and his pectoral fins and whiskers having some red streaks. When I first saw it on Tuesday night, I did not think it was something serious. It was until earlier that I discovered that his condition has worsened.

Worried that he might start to infect the remaining four Corydoras (1 Albino, 3 Leopard), we netted him up (again) and placed him in the hospital tank.

After searching the Net, it seemed that he had contracted Septicemia (source), a kind of bacteria infection. According to one of the posts of the thread, the red streaking observed on the fins or red spots on the body are the result of haemorrhaging of internal organs and accumulation of released blood in more external tissues of the body such as fins.

The causes for this infection are also countless, according to the post. Most likely he was being overly stressed when we first netted him up for his white spots, and being isolated in a small hospital tank, before being released back to the Main Tank.

After some time since the transfer, I decided to place some medication, Pimafix, which is known to solve reddish fins problem. After that, I continued with my other matters.

When I returned 15 minutes later though, I saw the cory flipped over, motionless. Saddened and stunned, I called Cat over, informing her that he had already R.I.P.ed. Just when I was about to do a final confirmation of his death, I tapped on the hospital tank glass wall, and he suddenly frantically swam about in the small tank.

We were surprised by his sudden ‘revival’, but quickly acted to remove 80% of the water, suspecting that perhaps the dosage of the Pimafix was too much for his frail body. I then topped up the water using the clean water from the Main Tank, thus achieving the dilution of the medication.

With that, he appeared to be better and rested at the bottom of the tank. Hopefully the overdosing shock did not damage him too much.

Meanwhile, we hope he will be able to survive through this ordeal…

Epistylus

Some friendly folks have responded to my post on the Arofanatics forum, and one has suggested that our cory could be infected with Epistylus, a type of fungus infection which grows on corydoras with injured spine.

Below are some information I’ve found regarding Epistylus (source):

Epistylus
Observations
: Balls of fungus, usually located on dorsal and/or pectoral spines.
Conditions: Epistylus grows on gravel and moves onto fish with injured spines.
Fish Affected: Corydoras, Pimelodellas, any armored catfish, and iridescent sharks are especially prone, although it can occur in any fish with injured spines.
Cure: A combination of malachite green and formaldehyde, plus the actual removal of fungus balls to speed recovery.

I am not sure if Pimafix, a medication we have that is well known for curing fungus and bacterial infection, contains the suggested ingredients. Anyway I have applied some Pimafix last night into the hospital tank in hope of treating him.

Also, someone else have had observed similar symptoms on his cory too: Link

Sick Cory…

Just as I was busying myself preparing for the water change scheduled tomorrow and netting up new sightings of guppy and gourami fries, something caught my eyes that provided with more activities to pursue.

One of our Albino Corydoras had a relatively large white spot at the back of his dorsal fin (read: top fin). This alarmed me and I know the first thing I need to do is to quarantine him. Cat and I took out our nets and started our capturing of the cory.

It was a really tough job, as we spent countless minutes trying to net the stressed cory out. He moved very swiftly and ducked all around the tank. It was most difficult when he hid behind the bogwood and vegetation.

After many attempts, we finally got him out of the tank and transferred him to the hospital tank, at the cost of disrupting the fishes in the Main Tank.

He was of course very nervous when he arrived at the small hospital tank but soon he settled down at the bottom of the tank, resting his body but breathing heavily due to his excessive ‘exercise’ while being chased after.

Currently I’m still looking for the best ways to treat him, though most likely we will adopt to the White Spot medication that we previously bought. Hope he will get well soon.
