I have a pond in the summer months and always bring my fish in over the winter,I do not keep them in a tank but in like a betta dish (the big ones)
I change water 2 times a week and only 2 fish to a bowl.They get so huge over the summer I hate to not keep them.I like the big black ones with the bulging eyes the best
Is your tank clean,maybe you need to take out half the water and refill it and put in a complete conditioner ( it will get rid of or reduce odor and organic slime and just make your tank a better enviorment if used weekly),it will provide a clean wholesome enviorment for them,or take him out and put him in a bigger jar with clean water till he revives or expires.(need to treat the water before you put him in it)
I have keep goldfish for 3 years before they have expired. DO you have a under ground water filtration ? |
