Oh no I'm so sorry! You've been very helpful for me on my thread!

I don't have a lot of personal experience but I've read a lot of articles. From what I've read whenever you see massive deaths in a tank, you should use bleach to soak this container that housed whatever might've killed your bettas because they get rid of 80% of anything that could've caused their deaths (except for tuberculosis and dropsy, of which there is no known cure, and if your pets had that throw away the tank, according to the article). I would do some research for the specifics though, and if I stumble on the article again, I will definitely forward it. Hope that helps, good luck!

Found it on bettatalk!!

u how to sanitize a bowl that housed a sick fish

1. Soak empty jar/bowl, fishnets, tank accessories, filters heater etc in a mixture of tap water and Clorox (1 part Clorox to 20 parts water ). WARNING: Bleach kills fish. Do not allow bleach to come into contact with your betta, plants, snails etc... Ever.

2. Allow to marinate for up to one hour.


4. Wipe dry with a paper towel.

5. I recommend you then let everything sit in the direct sunlight for one to two days. Sunlight will zap any residual bleach left in or on the tank/jar etc, so it will be safe for you fish to return to his home...

u how to sanitize a tank that housed sick fish

1. If a whole tank is infected badly, you might want to tear it down. Move all fishies to new quarters.

2. Empty contaminated tank.

3. Throw away any LIVE plants (they cannot be sanitized).

4. Remove all rocks and gravel ( rocks and gravel cannot be soaked in Clorox as they will absorb it and then probably poison your fish. Since I have always used natural gravel, I have always put the gravel and rocks in a tray lined up with aluminum foil and baked them in my oven at 450F for about an hour. Kills everything. Now if your gravel is coated, I hear it may cause some problems, possibly melt the coating. Perhaps you can test a few rocks and see what happens. If the coating melts, then try baking the gravel at only 250F and bake it a bit longer. Should do the job. either way, when done baking rocks LOL, let them cool off and put them back in your tank (AFTER YOU HAVE RINSED TANK FROM THE CLOROX/WATER MIXTURE).

5. The tank should be filled with water and Clorox should be added (same proportion as above).

6. Throw in there the filter (Throw away all the filtering media before soaking filters), heater, thermometer, any plastic plants, anything plastic.

7. Let it soak for a couple hours.

8. Then empty and rinse rinse rinse etc…

9. If you can (have garden or balcony) let everything sit in direct sunlight for a couple days.

10. Put brand new filtering media in your filter, and put your tank back together, fill with water and let it run for a few days before adding bettas to it. I recommend using “CYCLE” which helps reintroduce the nitrobacter which are necessary to your tank’s filtration. I also recommend doubling the dose of Amquel the first time you fill the tank, just to be sure.

u important warnings!

1. CLOROX KILLS BETTAS!!! Do not allow ANY bleach to come into contact with ANY living thing, especially your fish! It will KILL THEM pretty instantly (or within minutes).

2. Do not bleach plants.

3. Do not bleach rocks or gravel.

4. Do not bleach any ceramic ornaments .

5. You can only bleach safely plastic and glass.

6. Almost all bacteria are killed by bleach, but not ALL of them. If you are dealing with very very serious infection/epidemic, I recommend throwing everything away and starting over from scratch (i know it hurts, but take it like a man! LOL).

7. Air drying alone will not kill all bacteria. It may kill some, while others will live through it and flourish again once the conditions become right (adding water and new fish). hence air drying a tank alone will NOT sanitize it.

8. Hot water and salt will not kill all bacteria. It may kill some but many will survive. Hence bleaching is a much better approach (more efficient). Use salt and hot water for routine maintenance, but bleach for sanitizing contaminated tanks/bowls.

Well... What are you waiting for? Roll up your sleeves and GET TO WORK! (and make it snappy LOL)

its ok :) i learned from my mistakes.its sad that these girls had to suffer like that.but alteat not they die in vain and i can share with others to prevent it..thnak you missmayr also for the post.i was thinking about doing something like that but wasnt sure about the gravel and exactly how to do it.someone had posted on another thread that it might have been blood poisoning or something like that and it killed them off.i thought of getting the cheap feeder fish and putting in there also as a way to test and see how they react.i wanted to get feeder fish as a if they survive even better.

though i hate to put them through it.but they will be remembered and help save other fish life..again thank you :)
