Hi Terryansimon,
Personally, I feel that you are rather stupid and strange to put up such a post.
Firstly, if your tank is unable to provide a good stable home for your fishes in long term, you shouldn't buy or keep in the first place. Or you didn't expect them to live longer than your expectation?
Secondly, you wish to land them to good home with good husbandary but the would be owner just mentioned their tank size with their population before you sold it off. Would you sell it to me if I told you that I have a 6 footer with state of art equipment but only 2 week old in reefing? & btw, what is ich?
Thirdly, I believe it will be a good point that you are able to capture them and place them in a easier location for the would be owner to pick up later rather than asking them to catch while at your place. I would be at a loss if I am to "visit" you, sat for a few hours, making new friend ith you, but the primary objective still inside your tank and we admire from outside.
My truly apology if I have offended you in any way but I just have the feeling that selling in this forum is difficult enough without any salts added. (Should be added with water)
Lastly, another apology for being off topic but as you mentioned, PM is not your cup of tea and I respect you for that. That's why I posted my 0.000000000001cent comment here (Which in the first place, is not needed at all.)
UPZ for your sale.
