My mom bought a baby red marlburogh or somthin like that and it cant seem to stop catching a fungus or bacteria infection. im not sure what it is (disease) but its in a 15 and after a week it got it and i moved it to a tank with a bunch if medicine and it is fine in the morning. This has happend 3 times even after i drained the tank and did a 100% water change. the tank has a acidic ph and the tank is spotless with no amonia. Any tips for keeping this guy healthy?
