I have a female Flowerhorn named Camillia. We have got her for about 2 days now. On her first day she swam around her tank learning the environment. The next day we noticed that Camillia kept staying on one corner (Near the water filter and the water heater). She wouldn't get out of that spot. The shopkeeper who sold Camillia said that she loved eating dried shrimp. We simply followed and she did. She would only swim up for food and sit back down on the aquarium floor. The shopkeeper said that she also ate live fish weekly. Today is her weekly live fish feeding. We gave her some live fish and refused to eat them. Starting from yesterday (Today is her 3rd day with us) we noticed that she wouldn't swim around anymore. Is she sick? Is there a way to save my poor fish?
