You could ask but imo it’s steep. Let’s say
400ish for the big colony and 100ish for the 2 head would be min I would try for.
Maybe ask 600, be prepared to come down to 500, and anything in between accept and call it a day
Or. Since you’re good at growing corals, maybe you can find someone willing to trade for something real high end, that you can grow out and sell for some big bucks
Example.
Banana holy grail and Holy Grail torch typically are $400 a head, if they are good ones.
If you could find someone willing to trade a head of something high end for your colony, it would be an investment that would pay out big in 12-18 months…
Started with one head banana holy grail
In 1 year it was 4 head
And by 1.5 years it’s 8+ Heads
Holy grail is also another high value item, I got this one as a splitting head and in a few weeks (after this photo) it’s become two head. This particular one is $500 per head from the vendor and on private market they go for approx 400 a head
