Hello. I've had this brunneus fairy wrasse in a pre-cycled 20g qt since last Tuesday. I did 24 hour prazi treatment on Saturday-Sunday, did a 5g waterchange, and have been running carbon to limit exposure. He didn't eat during the 24 hour treatment but has been since. He's getting more and more active so I'm actually getting to observe him now. I've noticed twitching behavior and I watched him scratch on pvc and an air stone(I think at the gill). There is a single spot on his left pectoral? fin but that's all I can see. I've never dealt with ich, so I'm not 100% what I'm looking for. I'm due to run the second round of prazi again on Saturday..Should I just wait and continue observing? I also have two tiny female fairy wrasses in there with them. No scratching and no obvious twitching. Nobody has labored breathing and, again, all are eating anything I feed. Thank you!
