Does anyone have experience/recommend giving all new fish a quick Blue Bath w/
methylene blue after bringing them home and before introducing them to the tank?

I’m especially looking for experience with Clown Loaches in this matter since they are a little more sensitive.
Possible a small amount in the bag for a few seconds before placing them into the tank or something.

Thanks for your input.

I get new fish into a bucket of MB (1ml per gallon) for an hour before they go into the QT tank. I match bucket water TDS with bag water and just net them into the MB solution. MB will get any pathogenic bacteria off their skin, boost immune, reverse any ammonia toxicity, and improve oxygen levels.

First I want to thank you for responding and helping me out. I'm enjoying learning from all the knowledgeable people here.

I don’t know what all those abbreviations mean though. I’m new.

MB = Methylene Blue. QT = Quarantine Tank. I'm guessing TDS means temperature or something along those lines? TDS stands for Total Dissolved Solids.

TDS May stand for Total Dissolved Solis’s But I don’t know what that means in the context.
Hopefully they explain a little further.

Oh no! I apologise. I'll try and be more descriptive. Although, I've never heard of a newbie using Methylene Blue either in my defense!

This is what I do because I don't trust all my fish sources. Most fishkeepers won't bother with this step. It's just an extra precaution. And I think I might be OCD or paranoid

I "rinse off" the fish in a bucket before they go into a Quarentine Tank for observation. At the same time, it's good for the fish, especially if they have been shipped for reasons I mentioned already. I match water parameters as best as I can between bag and bucket water. I've already added 1ml per gallon of Methylene Blue to the bucket. Usually my water is softer than bag water, so I add salt (sodium chloride) until Total Dissolved Solids are matched. Salt is another preventative bath, but I don't use that much either way. It doesn't take much! Sometimes only 1/8 teaspoon....or less! I got a TDS meter like this one

I net the fish from the bag (or pour water into another bucket pouring into a large net and capturing the fish) and add only the fish to the bucket. This is to prevent bringing in pathogens or parasites with the bag water. I keep them in the Methylene Blue bucket for an hour or so, lights down, still monitoring temperature so that it doesn't drop. I kind of get creative there. If you have a spare small heater, that would be ideal.

Then I net the fish from the Meth Blue bucket to the Quarentine Tank. If the differences in parameters between the bucket water and QT tank are too drastic, I'll either do a water change (enough to match Total Dissolved Solids) while the fish are in the Meth Blue solution or acclimate the fish to the Quarentine Tank water.

To acclimate fish, I'll add Quarentine Tank water little by little (a cup full of water every 10 mins or so) to the bucket until it's 50% QT/bucket water. Then I net the fish and transfer only the fish (without bucket water) to the Quarentine Tank.

Appreciate you!!

I was told by my local primarily reef/saltwater store but he has some freshwater fish as well, I was told by him about MB blue baths.

Thanks again, I’m enjoying learning so much from everyone.

Ok yeah. Probably because most saltwater fish are still wild caught and cost so much to buy. No worries, I'm happy to help if I can! Thanks all who had my back with the abbreviations as well
