[file] hi i am new and need help! My son has two oscars for about a year now. He thinks he knows all about them and he as done good with them but as the grandma i do my best to look out for their safty. Whats a fish grandma to do!!

welcome to the site,

if you have any questions just ask and someone is sure to help you out.

Welcome to the forum, I know grandmas worry cause so do moms.. Ask all the questions you like.

I think the two are fighting the one looks bad and i don't know what to do. been a mom of the 17 year old that has the fish i am trying to help them cause i don't think my son knows what he is doing!

How big is the tank they are in? How big are the oscars?

solution to your problem can best be addressed after a few question for you. firstly how big is your aquarium? are there any other fish in besides the oscars? what type of filtration do you have? and lastly what are the water parameters in the tank(ammonia nitrate nitrite and temp) ?

after you get us these answers we can better help with your dilema.

I'm sorry to have to break this to you but all 17 year olds know everything and their parents know very little if anything. Things will go back to normal when he has a child of his own then you will once again be the person that knows everything

55gal
just the two oscars
over the back
tem 74 and don't know the rest

How often do you do water changes? You need test strips or better yet a liquid water testing kit so you know when the water is dangerous to them. The strips are cheap but not as good, a liquid kit is around 50.00 depending on where you are.

i try to change the water but son gets mad and tells me "thats what makes the water go bad" I clean it about 25% every two mouths.I've had fish before and do know some what to do with them.

Do a 50% water change now!!!! And then go and get a Liquid water test kit asap. so you know when the water is bad... 2 oscars in a 55gal tank, that water should be changed about once every 4 days or so.
