- Do betta fish hunt? I saw the betta attacking and eating the pond
snails, which is fine. That's what I have most of the snails for
anyway, food. Last evening I canme home to find 2 dismembered dwarf
crays. Now I've had problems with deaths all summer, so that's not
new. Finding dismembered corpses is new. I watched throughout the
evening, and saw the betta eating one of the corpses. I began to
wonder, has he learned to kill his miniature tank mates instead of
eating his betta food like a good boy.
- I have found the few fish that can get along with various Cray's, generally
depend on size. Fish should be bigger than the crays, but not always.
Plecostamus are great and keep the tank algae down. They should be big enough to
shake off a cray fish if it grabs a tail. I prefer the white or lemon variety.
Larger Plecos don't have a problem.
Also great are Red Tail Sharks, always moving too fast for the crays to grab
hold of and they also eat algae.
I have KOI in a lot of the tanks with Crawdads and the only problem is
competing for food. Koi will sometimes eat cray food of carrots and corn but
generally let cray have it. Shrimp pellets will never get to the bottom with KOI and
if you feed want to feed them pellets let the pellets slide thru an area koi
can't get to.
Don't put in a gold fish as they will go after the crays. Also any fish like
white mountain cloud fish or neons that stay at the top of tank, and always
moving are okay. Hope this helps. Jerry
