Dimorphic? Good for breeding,bad for selling!

First topic message reminder :

So I get a knock at my door this evening and to my surprise it was the first person I ever sold a fish too. With them they had a bucket and 10 Walteri peacocks(females). Originally I sold these people the entire brood(20 or so) at $2 each, well half of them died in the last year and since I have gotten rid of the breeding group. Well guess what? They want their money back because none of them look like the males I had. After explaining originally that females looked plain and had no color they still baught them. So they got upset after I told them I could not help them and guess what?!!!! After they left I went out side to lock up my cars and noticed something on the tunnel cover from my Avalanch. YUP!!! They dumped all the fish on my truck and left. HAHAHA! I love it! Wish I would have walked out sooner and saved a few but it was to late.

How do you guys feel about selling fish that are dimorphic? or am I the only one that has had this problem.

Just got rid of some electric blue ahli's(1-2inch's) hope this does'nt happen again!

^^^^^LAME!!! i hate ppl like that! i know 3 too many ppl like your friend...its sad really but their tanks are cared for and cleaned often by me....just cuz theyre not my fish dont me i cant take care of em!

thats a trip i cant believe he had the b@lls to come back with that attitude.
Like Kory I also offer to swap the females but there not getting a male for each female i do explain that females will never get color only the males.
hope you never go thru that again and as you can see from everyones post Your Good.

As far as am concerned that is animal (I know they are fish, same thing to me) cruelty.
You should have called the police.

Well Dang, I will be the first to admit I am not a PRO at the selling aspect of anything. I am just a hobby guy who LOVES my fish. But theres NOWAY that I could possibly get upset with someone enough to lose any of them. I usually chalk up whatever happens to learning experiences and move forward. Some people are just JERKS

thats a brand new and strange story. as far as dimorphism goes evyone want the pretty ones, but through my numerous readings. a breeder can influence the sex of the offspring. with reptilesit can be temperature, or with fish it could be pH. i havent done enough research on the subject to be authoritative on the subject, but perhaps KMX can shed some light with his research superpowers.
