I don't know that the snails are bad, but they are so out of control! Bala sharks! Do they get really big?? I've read about a sort of catfish that eats these sorts of snails, too, but I can't remember what sort they are.
I have 9 fish of various sizes & a giant common pleco. I do frequent water changes but can't vacuum all of the gravel because of heavy freshwater plants altho I may have to do it to get the gunk that the snails are thriving on!
Thanks for the info about how much you feel Caril. I have TRIED to get my mom to listen to me about how much & often to feed.
Oh! I read today that another way to get a lot of snails at once is to put a bit of lettuce on a veggie clip & then pull it out when it's covered with snails. I've considered putting them in our bird bath for the birds to eat, but always worry about upsetting the ecosystem, ya know?
Thanks for the suggestions - keep `em coming!
Stay calm and carry on.
