I was in the middle of moving to a new house and most of the tanks hadn't been moved yet. A lot of fish from different tanks got temporarily housed together while the tanks got broken down and moved. These two Catfish had been housed together while younger and both were pretty chill, so I figured there was a good chance they'd be ok together in a smaller tank for a short while. I kept an eye on them just in case and luckily there were no issues.
I am a fan of JDM, but it's not something I do with my own fish.
