Cover the filter where the bubbles come from (like something nontoxic) then put a rubber band around it, so it doesn't suck them up .. I wouldn't put them in a fish bowl because it is too small, plus they will find some way out..
Hope this helps :)
Fresh water crayfish feed upon carrion, small fish and water insects, but the majority of their food is algae and water-type plants. They also filter feed. Saltwater crayfish are also filter feeders, but scavengers too and often feed upon fish carcasses and regularly prey upon urchins.
you get someone to help you set up your bowl
yes
Crayfish are not fish, and they love to eat fish if they can catch them.
A crayfish is not a fish because they have bones on the outside of their body fish don't.
The crayfish isn't a fish at all - it is related to the lobster.
Crayfish will actually attack fish. It is best to keep them separated.
i feed mine 4 minnows/baby fish. a favorite is dead blugill
it is always good to get some kind of filter for your fish, but natural ponds dont' always need one. the filters will keep out some bad bacteria though, and keep your fish healthy longer, and allow you to actually see them. goldfish are very hardy and can withstand quite a bit.
yes, crayfish do eat fish food. i feed my crayfish fish food all the time
