My dad just adopted about seven fish one is an adult Jack Dempsey and and adult Oscar. neither will eat any thing. all the others are eating just fine. What is wrong you think?

Maybe they're just stressed, or not used to the food you're feeding them.

What exactly are you trying to feed them?

Some additional info would be helpful.
How many and what kind of fish?
What size tank are they in? If this is your 55g, I'm afraid the tank may be overstocked .
Is the tank cycled?
Do you now what the readings are for ammonia, nitrite and nitrate?
Are you fedding the same thing they're used to eating?

With all the questions, it might just be that they need time to get used to a new home.

Usually fish like those when moved wont eat for a few days or more. When I had my JD, I moved him and he didn't eat for two weeks! Your fish are probly just settling in. Don't stress about it. They will eat when ready.

BTW...your tank isn't big enough for all the fish you have. An adult Oscar alone needs a 55-gal or bigger.

Can you please put in the date your tank was started. It says 7-days old. Thanks

Denman

Yeah thats what i told my dad. He has a bumble bee, 2 convicts, some others they are in a 75 gallon now. The guy who had them before my dad had them in a 55. And we have been feeding them the same stuff the first owner fed them so they are probably just confused.

Lucy

Yeah, give them some then. I know it's easy to worry when something isn't what we expect.
Good luck

Lucy

So as not to confuse things, I've moved dogman432's question here:
