Hi, so our red ear started making a somewhat loud sound like a cough about a month ago. It was a few times daily. We ended up changing the water and cleaned the tank and the next day she was quiet. It has been 2 weeks now without her making that sound but she started again yesterday. She did it a couple times yesterday and once or twice today. The water in the tank is fine this time. Her behavior is fine but I just am curious what this sound is! I tried attaching the file so you can hear it, but the post isn't allowing the file. I can email it if you need to hear the sound.
I just bought her a multi vitamin today to help with a supplement in case she needs that too.
Let me know if you want the file sent to you to hear the sound.
Thank you
