Good luck, Milton. The market is wild and unpredictable right now. In my experience lately with colonies is you will either get lowballed, or if the pot is sweet enough, somebody will grab and then most likely chop it up and resell.
so if you’re not in a rush, and you want the least amount of work, try and move it all together and be prepared to take a few weeks.
If you don’t mind about the monetary loss, price it all to move and then begin your next tank configuration.
if you want the most amount of money (which means the most amount of work) dice them up and sell frags. This means you’ll have to deal with more people as well, and as stated, you don’t want to go this route.
You could give them to the club and we could potentially frag them out for members at the next meeting, no matter what, you’ve got options.
