ich in clowns, what to do about meds

Post by martinchristopher » Mon Apr 30, 2012 10:59 pm

* 3 clown loaches, 4-6 inches
* How long has the tank been set up for? 18 months in a 35, but just moved to 55 1 month ago
* Size of tank (dimensions and volume). 55 gal
* How is the tank being filtered? 2 powerheads on undergravel filter, plus 9 watt UV steralizer
* Water temperature. 86 for 4 days
* Your maintenance regime (e.g. how often water changes are carried out, what percentage of the water is changed each time, how often you clean your filter/s and how do you do this?) removed carbon as part of med treatment, water changes usually 20% every two weeks or so
* Has anything new been added to the tank recently? (fish, plants, live food, decor etc). yes, unfortunately I added 3 new cats without quarentining
* What other fish are in the tank? 2 large angels, 2 tetras, betta, and the new SA bumblebee cats which I think are dead
* As detailed a description as possible of the symptoms the fish are exhibiting (remember a photograph can speak a thousand words). ich
* How long ago the affected fish were added to the tank, and how long the fish have been displaying symptoms.
* Your current water parameters - ammonia 0, nitrate 20 ppm, pH 7.6, nitrite the tests strip is screwed up - reading green instead of pink, but we think this might be part of the problem

Thinking back, the clowns were probably sick before we moved into the new tank. Had a well established 35 gal., but it got a leak, so we moved everyone into a 20 that we had in the garage. Crowded but we were keeping the water clean while getting a 55 cycling. The clowns were hiding so much we thought that one or more might be trapped in a decoration. Finally got them out by blowing bubbles into the decoration, but this stunt probably stressed them pretty bad. Then we moved them into the 55. Went and bought some new fish to fill up the bigger tank. Didn't know loaches were so susceptible to ich, and didn't quarantine the new guys. The new ones started flashing after a few days. Sort of ignored it until the biggest clown started flashing on April 23. At that point, we raised the temperature first to 84 then to 86. We bought Ich Attach the same day and add a full dose twice a day, per the instructions, with the most recent dose this morning - the 14th treatment. Tonight one of the clowns looks almost dead - he has a very thick coat of white spots and was on his side not is the usually clown way but looking ill. We checked the powerheads to find that one was barely flowing. Added a bubbler and now we have alot of flow now across the top and the clown looks a little better.

We bought Coppersafe and added 1/2 strength dose tonight. Then we got on here and started reading more to see several people post not to mix meds. We are starting a large water change - the sticky suggests 50%.

Assuming we still have clowns in the morning, here are my questions:
1. How much water change, how often, for how many days
2. keep using Coppersafe? If not, then what - temperature and Ich Attach haven't worked. If yes, how much, how often?
3. Should we do gravel vac? (yes, I'm pretty sure) The tank is heavily decorated with rocks and plastic plants -should we move the stuff around to vac, or pull it all out until we solve the ich problem? Will lack of hiding places stress them worse?

We love our clowns and sure hope we can help them!

Do daily or at the least every other day water changes that emphasize gravel vacs.

Dose per label direction which ever meds you have chosen to use.

Do not run UV with any meds. Many meds are broken down when exposed to light, and UV is very strong light.

Increase aeration in the tank. You might do this with a bubbler, or allow the water level to drop a bit so water returning from the filter splashes a bit, and certainly making sure the power heads are running properly is important.

The usual course of Ich:

Ich arrives in the tank, and you cannot see it. May be hidden in the gills of the new fish, or just attached to the fish and still a single cell, so you cannot see it.
Ich grows, falls off the fish and reproduces. This may take a few days if the Ich just got on the fish in the store, or it might happen right when you add the fish to the tank. The shock of the water change (from store to home water) might make the Ich fall off. Ich babies may also have been swimming in the water from the store. So, even at the beginning there may be Ich in several stages introduced to your tank.

Ich babies land on the original fish in the tank. You do not see much for a day or two, but as the Ich grows and the fish is irritated you see white spots and flashing. As several days go by you see more and more white spots show up on the fish. These are Ich that landed on the fish a few days ago, when they were too small to see, and have been growing.

When you add medicine you are killing the babies that swim in the water. Any Ich that is on the fish are covered with the fish's slime coat, and are not killed. You will continue to see new spots show up for a few days after you start medicines. Remember Ich lands on the fish and is too small to see for a few days.

However, to continue to see more and more spots after the first few days of medication (say a week at the most) suggests the medicine is not killing the baby Ich.

Your UV is not working, or the Ich is not getting pumped through the UV, and the medicine might be getting broken down by the UV. This is not a contradiction in terms: The bulb might be weakening in the UV. It might be strong enough to affect the medicine, but not enough to kill Ich. Or, the water from every corner of the tank is not passing though the UV often enough. Baby Ich is finding its way to the fish before getting killed by the UV.
-------------------------------------------------------------------------------------------------------------------------------------------------------

Here is what I would do:

1) Separate the fish according to how high a temperature they can tolerate.
2) Put them in bare bottom tanks. High water flow, a rock or two, live plants are OK floating in the water, not on the floor of the tank. Split the filter media the same way you split the fish: If 75% of the fish are in the warm water, then put 75% of the filter media in that tank. The filter media has a lot of nitrifying bacteria and both tanks will need these bacteria.
3) Increase the temperature in the tanks to the maximum the fish can handle. Higher than 86*F for the 'warm water' fish.
Perhaps upper 70s, or at least mid 70s for the cool water fish. You can raise the temperature pretty fast, a couple of degrees a day, easily, perhaps faster. If the fish are stressed for oxygen (poor gill efficiency because of Ich in the gills, and warm water holds less oxygen) then increase the surface movement of the water to raise the oxygen level.
4) Add UV to both tanks. Get a new bulb for the one you have, (Unless the bulb is less than 1 year old) and make sure the UV is rated for a larger tank than you are using it on. Make sure to set up the water circulation so it all passes through the UV. Check the manufacturer for proper flow rate to kill Ich. It varies. If the water passes through too fast Ich is not killed.
5) Add salt. A little each day until you have the full dose in the tanks.
For fish that are tolerant of salt: Add 1 teaspoon per 5 gallons every day for 3 days. Total dose is 1 tablespoon per 5 gallons. This may be so much the plants do not like it and die. Plastic plants are OK to provide hiding places for the fish.
For fish that are not very tolerant of salt: Add 1 teaspoon per 10 gallons every day for 3 days. Total dose is 1 tablespoon per 10 gallons. Some plants might handle this.
6) Daily water changes that emphasize vacuuming the floor of the tank. Ich will land mostly on the floor, but also on the rocks that are there for the fish to hide among. Move the rocks and vacuum under them every time. Add salt to the new water equal to the concentration in the tank.

Continue treatment until at least 3 days in the warm tank, and a week in the cool tank has passed since you last saw any Ich. Do not drop the salt level right away with one big water change. Do weekly or twice weekly water changes of about 25% with no salt added. This will drop the salt level slowly over a period of about a month so the fish can adjust.
38 tanks, 2 ponds over 4000 liters of water to keep clean and fresh.

Happy fish keeping!
