Fed old food!?

[eliramos]

Hey guys so I just made a dumb move I had left out frozen mysis in a closed gladcup of saltwater from yesterday's feeding I absent minded my fed them again but after I dumped the food the cup smelled pretty bad
Do you think it'll make my fish sick??

No I don't. They will be fine. Fish are smarter than you think and if the food was bad, they wouldn't eat it
