Hello everyone so recently my brother had caught a koi out of a privately owned pond by request of the owner because it was destroying the ecosystem. It is currently sitting in a temporary quarantine tank for a few days. I am reluctant to add it into my pond because this koi is substantially bigger than all the other koi I have. I mean he is HUGE compared to the others. I have read that it shouldn’t be a problem, but I am still scared. The main issue however is that there is some sort of skin coming from his nostrils. I’m not sure if this is normal like some sort of shedding but I’ve never seen it before. If you could provide help about the skin coming from the nostrils and the size difference that would be highly appreciated. Also, if you are going to try and criticize me for what I’ve done, don’t bother as I will completely ignore and disregard the message, I am just looking for help, not for people to tell me I am a bad koi owner. And also what species of koi is this? [ATTACH=CONFIG]582665[/ATTA
