So---I'm completely in love with apple snails right now. And I'd like to set up a tank (and fishless cycle it) mainly for the apple snails---just 2 I think. I'm thinking right now of getting a 20 gallon long. And maybe housing the apple snails with a school of neon tetras and some kind of corycats. Wondering about advice on making this work....what's the best filtration system for a tank like this? What's a good substrate. I really like pea gravel---but is sand better? I really don't want to plant the tank---so decor will probably be artificial. What temperature is generally agreed on as best for apple snails? I've seen the big ranges on care sheet pages----just wonder what the majority of people do for heating their snail tanks....Plan on feeding the apple snails blanched veggies and algae wafers as main staple of diet...anything else I should know? Any common pittfalls in snail keeping I should avoid? Do the corey and snails do well together as they are both bottom feeders? And if I eventually wanted to have like amanI or ghost shrimp---would they do well with the apple snails as well? Or are there any suggestions about stocking a 20 gallon long with 2 apple snails and any other appropriate tank mates. Thanks in advance---and sorry for the 8 million questions. Just excited to get started!
