So here is my flowerhorn story, My flowerhorn was just swimming so jolly like it bumps the glass when he sees me coming to feed him and now i noticed that there are white, 2cm in size and thread like worms around the aquarium and then so it was my school days so what i did was just transfer him to a a 3.5 gal container and put the oxygen in too but the badest news was that it was thursday then my classes ends at 12 noon of saturday so i let it go for the day to come but the container i used was gettin dirty so i made a 25 percent water change with the flowerhorn in and then so he was tiltly swimming but then i started adding water like just using a 2liter pitcher so that the pressure won't be that much but then after the water change it started to swim downwards and started to float like its belly is at the surface of the water and then he goes back swimming normally again so i didn't mind it but at the next day i was late for the class and then so never had a chance to see him if he was fine an
