Might be worth posting in the WTS section or something, and see if you can find someone who can rehome him.
We have a massive amount of responsible fishkeepers here who could rehome him, they just need to know about it
Even if just temporarily.
If it was me I would move him somewhere and tell them it died or something, then take it back in a couple of months time.
Law is very different here, if a law is passed like this it would mean you cant keap fish from the date of the law, but any fish from before the date of the law would be OK.
Aloit of laws here like that, most notable are car laws with exhaust noise etc, cars before the date are exempt from the new law.
