Hi, my betta is having similar problem. My male betta is having the below wound for last 6 days. It has stopped eating since then. Initially it was residing in a fish bowl and I had added half a capsule tetracycline to the fishbowl water. Now I've transferred him to a 9 litre acquarium 2 days ago (mixing the medicated fishbowl water alongwith) and kept the heater temperature at 26 degree C. Today tried him to feed a boiled and peeled pea. He has eaten a little. He has gone somewhat quiet nowadays. Any suggestion will be of much help. Thanks in advance! Please help what is the next step. I'm not sure of the disease he is having. Please help!!
