Trichodina Ciliated Protozoan Parasite, Symptoms Identification and Treatment

This saucer-shaped parasite is over-rated in its pathogenicity (not a big fish killer by itself but sure does cause self injury.) although I have seen it cause spider web lesions in the skins of Koi. The most serious damage it may do is to the gills of smaller fishes. This is one of two or three parasites that causes scratching in Koi, with few serious side effects. The most important thing about Trichodina, is that when it is discovered, it belies a problem in the System Housekeeping department. 

You can bet your license that there is some accumulation somewhere of mulm, and lots of it. TRICHODINA clears easily with SALT, and in very short order. You need only leave salt in for a few days to clear Tricho for good. 

Trichodina

Trichodina is a common pathogen of Koi, goldfish and pond fish. This is a unique pathogen in several ways. First, Trichodina is problematic in tanks that are rich in organic debris and detritus. In some instances, researchers have found that by maintaining fish in very clean tanks, Trichodina was self-limiting. Trichodina is also unique in its ability to remain pathogenic at very low temperatures. An example of such temperatures would be Koi, goldfish and pond fish pond conditions in the mid-thirties [oF]. While an inexperienced clinician might dismiss the possibility that the symptoms are related to a parasite in such cold water, a more cautious one might utilize the microscope and verify the presence of this common pond pathogen.

Trichodina’s other ‘special ability’ is its occasional resistance to salt at 0.3%. Indeed, there are few cases wherein salt does not clear up this parasite, but when this occurs, it can be serious. In most instances of salt resistance, double and triple salt levels clear the pathogen. You should be aware that otherwise healthy fish will survive salt levels up to 0.9% [zero-point-nine percent] which is achieved with three tablespoons of salt per gallon. See the formulary for information on this technology.

The clinical appearance of fish under attack by Trichodina is primarily epidermal. The fishes’ skin will appear irritated. The Koi, goldfish and pond fish will “flash” and scratch conspicuously. Eventually, the damage to the integument [skin] may eventually result in sores or ulcers. It is important from a practical standpoint to note that Trichodina is not the only organism that causes flashing. Inexperienced pundits have sometimes asserted this.

Ambitious hobbyists may collect a surface biopsy from the skin of affected fish and view it under the microscope. Trichodina appears as a flat, saucer-shaped organism. It is easily seen at relatively low magnification. I typically make my observations of this organism at a combined power of 100-200X. On closer examination under the microscope, the organism is fringed on the outside margin by thousands of tiny cilia or hairs. Inside the saucer, there are varying numbers of teeth or ‘denticles’. The actual numbers of rings and denticles determines which of the many sub species of Trichodina is being examined. Honestly, I have never been able to determine the clinical relevance of determining the subspecies of Trichodina. They all die the same.

This is The LCD Screen Scope
We Did The Tutorial With. I did a twenty page tutorial (Here's the tutorial) with video, audio, images and even little parasite movies to show you how to use a microscope. 

This Filter is Good For BIG Dirty Tanks
I've been wrestling with water quality with the turtles. The sponges work GREAT, but in THOSE turtle systems where they eat MICE the poops are bulky. This filter can handle it. In "Tortu's" tank, it's got an 800 gph pump and it rocks. 

PraziPro for Flukes
They nailed it. Figured out the solubility and worked out the dosing. It works. 

Buy Some Good Koi?
No, this isn't really for the 'high end' collector y'all. But for someone who isn't near a decent garden center, here are "good-to-quite-good" Koi you will like at a very good price. I know these guys personally.

Best Food, Ever
It's made for (and I discovered it for) my Blood Parrots but the small size, intense color enhancers and excellent formulation make it superb young-Koi food. Oh, and it's AMAZING on color-cichlids like Flowerhorn and Blood Parrots. 

Pro Air 60 Aerator is a VERY high output air pump pushing my whole fish room (17+ drops), and I have one at home driving everything there, and I have one as a back up. 

Formalin Malachite (Not dilute)
There are formalin malachite preparations at 10%, 22% and 37%. There's economy in the concentrates. Hard to get Prime shipping because air transport is curtailed. This is a good value on 32 ounces. 

Topical For Koi and Pond Fish Ulcers
I like 7% tincture of iodine because it stains but it's hard to hurt anything with it. Used with a WOVEN gauze, this works well to clean and disinfect a wound. Only use ONCE. Do not 'repeatedly' scrub wounds. 

Confectioner's Glaze 
Is the way to bind a medication to fish food. Gone are the days of paste food and oil. The write up is done, it's RIGHT HERE.

Koi Health & Disease
Hopefully this link takes you to the newest edition by PRIME to get it to your house the fastest. 

I have over ten of these Titanium Heaters in my fish room and at home. They're a paradigm shift in aquarium heating. They're titanium and 400W for under $30! Whaaaaaaaaat?

CyroPro by Hikari is safe and easy for Anchor Worms and Fish Lice.

Whatever heaters you use, back yourself up with a temperature controller, it'll turn on, and off your heaters. If your heater seizes "on" at least the thermostat will stop a tragedy. 

LifeGuard by Tetra is a tablet version of a tame 'chloramine-t' or 'halamid' compound that's easy to get and good on bacterial infections, in baths. 

Antimicrobial
If you're making medicated feed for a larger group of fish, this will come in handy. Dosing is available in the site. 

For me, filtration-of-choice
For aquariums, even small Koi holding facilities or small ponds. These sponge filters are cheap, easy to clean, and they clear hazes very well when used with some Accuclear or similar.

Rubber sided, round, nettable tanks
Make great hospital or quarantine facilities. They SHOULD cost about $200-300 depending on size, but this, lower quality unit (while panned in some reviews) may be good. Don't overfill and make sure it's propped up.

1200 Watt heater, on a thermostat held securely above the waterline, works GREAT as a large tank heater. That's all I'll say because there's risk of electrocution and all that. But then, even in a bucket you could get killed. Sound like fun?
I have several of these ALLIED PRECISION stainless ones that are a couple years old. Working still. 

Potassium Permanganate 
500 grams could be a lifetime supply but it's 50% more than the 100g cost wise, for 500% more amount. Dosing is in the site and the book.

What Does Ajax Eat?
I looked for something well formulated, with meat as the first ingredient. Something UNDER $2/lb and something they could deliver for free. And this was it. He looks and feels great on it.
