IMO rare is more to colors - true blue dragon, actual gold - I mean very bright (orange) gold, a show quality super black.... those are rare in my area.
All right just to clear things up i live in alberta about 45 min from edmonton where i am you find tons and i mean tons of HM, CT, and VT bettas i would need to order rose tails for example from another country probably and HMPK are all over online plus as for delta's and super delta's no one has even heard of them and don't get me started on round tails (spoon tails). So i guess it depends on where you live :)
I have an entire Pinterest page of betta colors I like. You may not be able to see it unless you do Pinterest too .. not sure. In case you can see it .. here it is.
Hi i am soon to be breeding betta fish and want to know what would you like to see ex: tail types, colors and so on
I will be breeding and shipping in canada i want to bring back some of the rarer tail types such as deltas, super deltas, rose tails, spoon tails, double tails and so on. i also might take into account some potencial buyers. Let me know what you think.
Also will maybe be doing draws on here so you might be able to win some of my betta fish.
If you know of any websites that sell less common tail types pleasse let me know.
Deltas and super deltas are not rare.. they are halfmoons without enough branching to get the 180 spread. Rose tails are not rare.. they come from excessive branching and except for some people, are not desired. And DT's.. I get 25% of my fish all the time as DT's.
