Good day. Please can i have some advice. My juvenile ornate bichir, i think, burnt himself on the tank heater. When i saw his injury i immediately did a 50% water change. Cleanes the filter and added salt. His tank mates are 2 apple head snails. A peter elephant nose and 2 other ornate birchir. My tank is 1.2m x 500 x 550. I do water tests weekly and 50% water changes every week and filer clean. My filter is a cascade pennplex 1200. My Gh Ph and Kh are in suitable range for all 4 fish. I noted today that hs seem to have fur on his injury. What can i put in ths tank other salt. Is it fungus or bacteria
