It's been almost a year since I bought my 2 GSPs & 2 Fig8's and to my surpise, they are all doing well and more so getting along great except the moderate tension during feedins which isn't unusual. I think having them only in my 55G tank with good quality water is the key. I'm concerned about their teeth. I've been feeding them ramshorn snails which I try to stock but I'm running out of tiny snails. Any snails bigger than the puffer's eyes seem too big for them to eat and if I crush the big ones and give to them, it really serves no purpose since they're only eating the meat mostly. Are there any other food available that can keep their teeth trimmed?
