My very first betta fish, who is currently chilling out in the floating wisteria in a 10 gallon tank, is a Delta tail named Howie.
While Howie is beautiful - he looks like a flower petal - I sometimes wonder if it is cruel to breed these fish to have such disproportionately long and fluffy fins. The fins certainly don't help him swim, and in fact, he sometimes seems to have trouble turning around sharply and loses his balance. He doesn't appear to move with the same ease as my double or crown tail, and certainly doesn't have the grace or speed of my females.
I'm certain that he is perfectly healthy, as he is friendly and alert and looks to be in beautiful condition (to my untrained eyes, anyway!). He just seems to be weighed down by these flower petal fins he's been blessed with.
So, any thoughts of these fluffy guys? Do they notice that their fins are heavy and cumbersome, or does it make no difference to them?
