Did I euthanize this fish right

Fishkeeping7777

I don’t know if I did it right but so there’s this fish that’s been sick for a long time I think it was because of bullying but there was no other thing to move it to so I was just medicating the tank just keeping an ion it so today the fish to swimming around fine but I noticed it was super skinny when I saw it at the bottom of the tank I thought it passed away but it was still breathing so not knowing anything how to put it down I did a quick Google search I didn’t have clove oil it said freeze so I got the fish I put it in the freezer and some water and right now it’s in my freezer did I do it right I don’t know I dug a hole in the backyard I just have to wait I am very distraught I really tried medicating the tank

Sorry for your loss. Anyone in the aquarium hobby will tell you that you loose fish overtime. In the future it is probably best to not use the freezer method. This actually can cause ice crystals to form on the gills and cause pain.

In the future you might want to look into using clove oil. There's plenty of information on that here and on google.

I took out the fish when it wasn’t fully frozen there was still water in the middle only the top had a thin layer of ice
Not trying to go off topic will my other harlequins kill each other I have only two in the beginning I had 4
But one jumped out and one got stuck in a hole

now there’s this one.
One is really bigger than the other when is like a baby and the other one is adult I also have three male guppies in there
It’s not easy for me to get them I have to go out of my city so is there any other fish I can mix with them if they will hurt each other if they don’t then I’d rather just leave it how it is

all my fish have been healthy for a long time so I wasn’t really expecting for one to die like that but I always need to be prepared I was thinking about getting some I just don’t know where does Walmart carry it

Yes Walmart should have it. It will be by the tooth ache medications. Its in a little brown bottle with a red cross on it. It will probably have little cotton balls that come with it. It will look like this.

Ok so what is your question?

Harlequin rasbora should be in a school of no less than 6. They are very peaceful fish, but they could get stressed from not having more members, and stressed fish are unpredictable.

I dont recommend the freezing method for euthanasia, I did always assume that a fish would be long gone before any ice started to form, but if you are going to do it, don't take a possibly half-dead fish out of the freezer to unthaw, please just finish the process.
In the future, if you don't have clove oil, blunt force or decapitation takes seconds.

I know they should have at least six i had 4 I wasn’t minding to get more but two passed away so now I have to and I just looked up a quick Google search I didn’t want to cut or stab the fish of course

Just to add my 2 cents about euthanizing fish quickly, if it is a small fish, say 2in or less it is best to take them out of the tank and drop them right into a cup of ice water. Just make sure the water is mixed up with the ice to get it as cold as possible and be sure the fish goes into the water part, not on the ice. The sudden change of temperature will cause the fish to go into shock and pass within seconds. Much faster and less traumatic than going into a freezer IMO. I've done it many times when culling deformed or sickly looking fry and it literally takes just a couple seconds. The only thing the freezer method has over the ice water method is you don't have to see the fish die, but you'll also know it is taking far longer to die than doing it most other ways.

Decapitation is not a good method IMO. Even if you cut the head off a fish, if you do not damage the brain the head will still be moving and alive. You must destroy the brain to properly kill a fish. I use a knife to "pith" aka stab the brain of game fish before I clean and fillet them for dinner. It is the most humane way to kill larger fish IMO.

I agree with this statement here for you future euthanasia needs. This is the most accurate from all the research I have done as well. I would avoid pithing a fish if you are not experienced though, because if you mess up its going to be more traumatic for you and the fish.



On the harlequin question: I believe that they should not really attack each other, but only having a 2 of them left will lead to more general stress compared to having 6 or more.

If I find any where I live I will definitely buy some if I have a quarantine tank set up but where I live they’re just not popular I had to go out of my city just to get those
