I'm a pond snail lover. I get them for free @ petco. 1st, they make great betta snacks! If they lay eggs- yummy treats again! (The pond snails lay their eggs above the waterline, so if you see a glob of eggs, just push them down into the tank.) If 1 or 2 survive, they munch on dead leaves & detritus. I have a few larger Ramshorns to help w/ tank cleaning. I surrendered my Apple snails b/c they were messy & the female bettas harassed them. My male betta is also a complete wuss about his apple snail, and will only build a bubble nest in a snail-free environment!
4 bettas: Butch, 3-year-old violet male PK EE & 3 girls in a 30 gal sorority. I do not name the girls anymore! 1/2 of them die within a month.
30 gal: 9 Oto cats, 4 Ocellifer cats. Inverts: Cherry shrimp & 2 assasin snails.
10 gal.: Butch, his 5 oto cats, 3 assasin snails, and a few snails the assassins haven't caught.
