Beta Fish

I think that we have had three beta fish as a family.  The first one lasted quite a while and was quite fun.  Then after some time we had to move and for various reasons it could not go with us.  Then after a lapse of years we got another which was extremely short lived, we thought, because we got it at Wal-Mart.  But the third one we go from Pet Smart lasted no longer so now we have unused Beta food.  I have not tried it yet.  The Beta fish as an idea I am not sure about.  The care is somewhat minimal, as are the benefits, but ours seem to die.  We are probably doing something wrong with the water, but what I am not sure.  So if you go out and get a beta fish, may God bless it with a long life in years.
