hi
i have 2 oscars.
one of them is powering ahead of the other.
my little oscar stoped eating so i pu tit in a seperate tank to it could get food. his been in there for abotu 3 weeks and still wont eat anything.
wat is goin on?

is the new tank cycled before homing it there?
if not, then you just aggravated the situation for him/her.
i suggest you bring it back to the established tank...just
provide a divider to avoid bullying.

Unfortunately these things do happen occasionally. I assume that he has tested the water conditions? Obviously that is the first thing you must always do. Have you tried feeding every day? You could try not feeding whatsoever for about three or four days and then introduce some food.

Maybe try live crickets, garden worms colourConway is always worth a try and can sometimes trigger them back into eating. Is the fish breathing heavily at all
