My opinion here only but .25 ammonia is lethal for lots of fish.
This is what i would do....
1) Stop feeding immediately.
2.) check and or clean aquarium for any decaying matter.
3) Carry out a partial water change.
4) Retest for ammonia to confirm near-zero reading(s).
5) Allow the aquarium two days further “rest” without feeding, etc.
6) Retest and repeat steps 1-5, if necessary.
7) If readings are near zero, then start feeding sparingly.
8) Continue to test water to confirm that filter is now coping with ammonia and nitrite production
