What to do with a naughty molly

For the last few days my collection of mollies in a community tank have been acting strange. Most the males have been hiding in corners, caves etc. After careful observation I noticed a young male was aggressively chasing every other male constantly. I removed the offender and the rest of the tank has returned to normal.
The Molly is a black sailfin lyretail that appeared as a fry from a black/ gold lyretail and I assume my black sailfin.
I have put him in one of my hospital tanks on his own for now but I don't know what to do long term. I don't like euthanasing healthy fish but I don't want him in any of my tanks. Normally I would take him to my local shop to re-home or feed to their carnivores but I'm in the UK under tight lockdown rules and I don't want to risk going to the shop at the moment. No one I know locally wants an aggressive Molly so I don't know what to do. Any thoughts?

Maybe by keeping him by himself for a few months he will get past his frisky teenage actions and will calm down. If after a few months he still acts the same it will be time to take drastic actions. Hopefully he will calm down though.

I will keep him until I need the hospital tank for another use, then I will try him again, if that doesn't work I think it's clove oil time. (I had a Cockerel that kept attacking people recently and he ended up as a roast dinner but I don't think a Molly will be much use.)

Sounds like the perfect ending to an unruly Cockerel/Rooster. Many years ago we had one that would attack anyone that turned their back to him. He spurred Mom one too many times. He ended on the dinner table too. Guess a molly wouldn't be worth the trouble of cooking him

 

It might just take some time. One of my very first mollies would chase the others around all the time. Tried putting her in timeout several times but it didn't help. After a few months the 3 mollies I had established a hierarchy and she stopped being aggressive.

 

Put him in a netted breeding box. Thats what Im doing to my aggressive platy.
