Pomacea canaliculata: Proven Predatory Instincts

How does a snail catch a healthy fish? I have some anentome helena who eat snails, but other snails don't move very fast. Maybe some bottom feeding fry?
They drop on their prey and latch on it. This is how some owners have described what they saw as they watch in horror the snails nibbling a fish alive. Boy...What a painful way to die.:hypnotized:
 
:eek: They parasnailed right onto the fish!?
Yes. How else would they be able to get to their prey?lol Most fish actually do not sleep at the bottom. Some drift at the surface but as baby apple snails love to float around to funnel for food, they also use this ability to parasnail right into their target. Most snails hunt in groups, some just individually. I believe my baby canas actually hunted them in group as I notice wherever the lot go, some hang out together.

I've never had any cannibalism in my snails, toward other species, fish, or other canas. I'm not sure about your shrimp pellets, Lupin. I feed only fresh veggies with no pellets of any kind, except snail cookies made specifically for snails. Perhaps it's the protein that sets them off? Mine get only kale, collard greens, carrot greens, lettuce...
They never tried to attack my goldfish when they were in together, either. I'm wondering if it may be genetic - some populations are cannibalistic, others not?
 
The crude protein is 38% in the shrimp pellets. Surely, the veggie protein is different from animal protein in the case of veggies. As for the snail jello, ingredients are only honey, baby food (squash/carrots), unflavored gelatin and calcium pills. Would it be possible the disappearance of the hatchlings during my vacation have something to do with this unusual behavior, in your opinion? The cannibalistic tendencies have been triggered by consuming other snails? I didn't leave anyone instructions to feed my snails during my 7-day absence last December 15 as I refused to trust them knowing they will only end up overfeeding my tanks. The only ones left when I returned were the older siblings and they were larger than I had seen them before.
