Sohal no eating

[Tanthaitrung]

Dear all,

My sohal was in tank (217 gallon) from August 2017. He is now ablout 12 inches.

From March 31st I dose RedSea NO3-PO4:X 30ml daily to control NO3. From 13th Saturday my Sohal was not eating, his skin does not show any strange thing, all the others tang are eating well and the parameters are good.

Could you please help me?

Thanks so much

Any new fish added recently? Or a new coral or invert?

 

[Tanthaitrung]

Thanks Humblefish
Yes, some peppermint shrimps and a copperbanded was add few days ago to treated aiptasia
I dipped the copperbanded 5’ with RO and 1 hour with Seachem Paraguard before adding tank

Carbon dosing lowers available oxygen in the column and this is a big fish.
Make sure you have, or continue to provide good flow and break the surface.
Watch behaviour very carefully And be ready to treat all quickly in QT, if
A parasite is suspected
What is the level of nitrate your trying to lower?

It's possible for some parasites (and other pathogens) to survive a 5 min FW dip + Paraguard bath.

I'm not saying these new additions are for sure the cause, but if this is the only recent change I would be watching your fish population closely. In addition to white sprinkles and other visible physical symptoms of parasites, it is important to observe for these key behavioral symptoms as well:

1. Reduced or complete loss of appetite.

2. Heavy breathing, scratching, flashing, head twitching, erratic swimming behavior

3. Swimming into the flow of a water pump/wavemaker/powerhead (unique to Marine Velvet Disease).

4. Acting reclusive (velvet causes fish to be sensitive to light).

Thanks for your response
The nitrate is now ~10, my target is 2.5 - 5

Thanks so much Humblefish
I will follow your advice

Dear HumbleFish,

I watched him carefully and he has the behavioral symptoms as you said.

I just picked him out, and dipped him in 3 liters of new saltwater with 15 drops of Formalin MS for 50 minutes.

He is now in a 3 gallon new saltwater plastic container with an air pump and 6 drops of Formalin MS.

I’m planning to leave him there until the day after tomorrow, then discarding the water, changing another plastic container and the air stones, doing one more dip and leaving two days with 3 gallons of new saltwater + 6 drops of Formalin MS then bringing him to the quarantine tank.

What do you think about my plan?

The instruction of Formalin MS said: “Use 2 drops per gallon of aquarium water every other day ...” That means every 2 days?

Does the Formalin MS has expiry?

Thanks

 

[HumbleFish]

37% formaldehyde (active ingredient found in Formalin-MS) has ~ 2 year shelf life.

With regards to your plan, did you notice the fish swimming into the flow of a powerhead?

If so, that is a strong indicator of Marine Velvet Disease: https://humble.fish/velvet/

Could you please show me how to read manufacturing date?

Most of time he swims normally. Sometimes hiding, scratching, standing in front of the power head. I’m not sure it’s ich or velvet but all other tangs are normal.

Formalin MS can treat ich and velvet?

Formalin MS can treat ich and velvet?

Formalin can provide temporary relief, but only copper (or Chloroquine) can reliably eradicate both parasites.

I'm not really familiar with Formalin-MS. Is there not an expiration date somewhere on the bottle? The company that made it (FishVet) is now out of business.

Thanks so much for your help

Hi HumbleFish,

1- Chloroquine Phosphate and Cupramine. Which one is better and safer?

2- Could you please show me how to treat with Chloroquine Phosphate?

3- Do I have to turn off skimmer? Activated carbon can remove CP after treating?

4- Can I use CP-500mg that sold in pharmacy?

Thanks

[HumbleFish]

1- Chloroquine Phosphate and Cupramine. Which one is better and safer?

For the time being probably copper (Cupramine) because it can be tested to ensure a therapeutic level is being maintained. No practical test kit exists for Chloroquine.

2- Could you please show me how to treat with Chloroquine Phosphate?

You dose once and treat for 30 days. Dosage range is 10-20 mg/L. However, Chloroquine is susceptible to biodegradation so its best to treat in a sterile QT and control ammonia with reducers + water changes.

3- Do I have to turn off skimmer? Activated carbon can remove CP after treating?

I would turn off the skimmer, and carbon does remove CP.

4- Can I use CP-500mg that sold in pharmacy?

You can, but if using the tablets then know that 500 mg tablets have an equivalence of 300 mg chloroquine base. So, you'd want to dose according to the available chloroquine base.

Thanks so much HumbleFish,

Seachem told me his ionic copper (Cupramine) is not absorbed into rocks or substrate and it's safer than chelated copper. But the fish treatment guidelines from reef 2 reef said the chelated is the safer.

- Who is right?

- Do you think activated carbon can remove Cupramine (ionic), Coppersafe (chelated) from rocks and substrate?

Best regards
Khanh

 

[HumbleFish]

Well, Seachem is wrong (or lying) about ionic copper not being absorbable. I've never really been impressed with their tech support.

As far as which copper is better, it probably just comes down to personal preference. I prefer chelated copper primarily because it has a wider therapeutic range. So more leeway to play with.

 

[Tanthaitrung]

So activated carbon can not remove 100% both copper from rocks and substrate?

 

[Tanthaitrung]

If you don’t mind, I some questions

1- Activated carbon can remove most of medicines like CP, General Cure ... from rocks, substrate, except ionic & chelated copper?

2- Coppersafe, Copper Power are chelated copper. Coppersafe instruction is 1.5 - 2ppm and Copper Power is 2.5ppm. Somebody told the instruction of Copper Power was wrong. I’ve got a bottle of Copper Power on hand, should I keep 1.75ppm when treating?

3- I’ve got a quarantine tank with live rocks, I think it’s not good if treating fish in this tank with copper or CP. It’s will be better if the fish is treated in the tank without rocks and substrate. Am I right?

4- I saw your instructions from humble.fish. That the treating period can be shortened by transferring fish to quarantine tank after 2 weeks of treament. Do you think 8 days treating with copper or CP + tank transfer method (transferring every 48 hour x 4) can eradicate ich and velvet?

Thanks in advance
