Its probably sleeping.
It either got ich or just inflated
Obviously it is unhealthy. Just let it go on with its life and it will die when it needs to.
It's sick and/or dying.
Puffer fish are very aggressive fish and will tear the poor goldfish to pieces.
Siamese fighting fish lay on the bottom of the tank because they try to play dead
yea it ate all my other fish. put them in a separate tank with some other puffer fish's roughly the same size. :)
Well usually puffers are kept in species tanks but puffers can tolerate corys or smaller plecos but only with some puffers e.g amazon puffer or pygmy puffer or figure of 8 puffer wheras a congo puffer will eat pretty much any other fish in its tank .... Also puffers are fin nippers so no long fined fish or fantailed fish
Take them out and add what you forgot most of the time is water solution
Nunners here, I was wondering which puffer fish you meant because some puffer fish release poison when they inflate, thus killing themselves and other fish in the tank. Or if you get the one that has shark spikes it could wound your goldfish causing it a cut, he could die because of an infection. Also i think puffer fish are tropical fish?
im no expert but i presume theres something wrong with it. Try going to the pet store from where u got it from and ask them. Search a smart fish site But just move it from tht position and possibly check everything in the tank is ok
Yes,the Oto will clean the puffer's leftovers(puffers are messy eaters)
It cold be time to get a new fish. I'm sorry for your loss
You are supposed to have bubbles in your fish tank or else your fish will die because they don't have enough oxygen.
