If I ever left my fish for a vacation... I'd pick only certain people. I also, once, had left the spawn pair, free swimming babies, and others in the hands of my friend.. I put sticky notes on each betta tank "feed me three times!" for Admiral, "don't feed me while I'm with my babies!" for Maine, "feed me twice!" for Madame, with amounts :) because for some reason I have special bettas who need more food, or less food o_O
Breed for the breed, not for the money; the words any REAL breeder would understand.
You must know nothing in order to know all, for all is nothing and nothing is for all.
