I feed my habrosus cories with a sinking wafer, which they love. Unfortunately, so does my VT betta girl, Ann. Even if I try to distract her with her own food while I drop in the wafer, she hurriedly eats a pellet and then dives down to grab the wafer. She carries it around in her mouth, looking completely ridiculous, and bites off little pieces of it at a time. I've tried to distract her time and time again, but she always goes back and picks up the wafer again. The way she tears it apart, the cories get a good share, but Ann gets quite bloated. I'm sure it's not good for her because she is eating a LOT, and the wafers have some plant matter in them.
I recently put her in with a sorority with five other girls, and that helps a little -- because one of the more aggressive girls will sometimes come to see what she had and chase her until she drops it - but she's still eating enough of the wafer that her little tummy looks too bloated. None of the other girls are interested in the wafer at all, so it seems like it's just an oddity with this one girl.
I tried turning off the lights when I drop the wafer in, and that way it takes Ann a little longer to find it, but she still finds it.
This happened again today so I put her in my 2g hospital tank with some epsom salt to hopefully help with the bloating. But ultimately she's much happier in the big tank, and I don't want to separate her out permanently over something as silly as a food dispute.
I would just separate her out every day while I feed the cories, but I'm afraid that will stress her out needlessly.
Is there anything else I can do to discourage her from eating food that isn't hers?
