Good morning,

I had a trio of lithobates and over the past 2-3 days I noticed the male has lost all colour, was acting lethargic and not eating. He didn't really have any injuries and no fungus or anything exterior I could see. One female is holding and all other fish are acting pretty normal. Not sure what to think and why he melted so quickly, he passed this morning after I separated him into a breeder box thinks by it could be stress. The pics I took were from the night before after separation. Any ideas would be appreciated just looking to understand what happened. Thanks in advance

If you don't come up with anything else, I would assume harassment. Watch the others to be sure they don't develop symptoms. If they do separate them sooner...and into a hospital tank.

Also observe the tank closely...I would expect one of the others is a male. If you are able to confirm I would separate the 1m:1f to keep the female safe.

Once you are past the emergency in a month or two I would add a bunch of females.
