Dear Faith, I have a
pair of blue and a pair of pastels and the blue male has great genes
as does the pastel female in your opinion would it be wise to breed
I guess it all depends what you are trying to accomplish. In other
words, what are your goals? It is always best to have goals when
breeding, otherwise you will be spinning your wheels for nothing and
wasting a lot of time. Having said that not everyone is after set
results, some people just want to have fun and there is nothing
wrong with that. In that case, one could breed any two nice bettas
together, just for the fun and experience of seeing a spawn
happening and raising fry.
Now back to your question. You did not mention what color the pastels were. I assume blue, which is the most common. Solid blue and pastel blue would not be a bad combination, they are actually pretty compatible. Although I personally have not done such a cross (because I have not been after the results it would yield), I have been told that you will get more blue (or possibly greens, depending on what color your pastels are). You will also get down the line more pastels, possibly also butterflies. What you want to make sure is that your bettas are clean, meaning have no red washes. Red washes on either blue fish or pastels are not desirable. Good luck, and remember to have fun!
