Actually what I used for the partition was 1/4" square plastic grid "egg crate". It's a light diffuser for dropped ceilings and is about $12 or so from building supply places. (sometimes in the ceiling section instead of the lighting section. Just crammed it in 3" in front of the back glass and held it in place with rocks at the bottom and power heads at the top. I also added 2 utility lights behind the tank pointing forward. (2 tube florescent that cost ~$20/fixture with tubes.I'm planning on getting a 5-10 gallon HOB refugium setup tomorrow! Hopefully this works well as it is $60 from my LFS. Your route sounds like it could work too-I'd just use fish-safe glue and have a piece of glass cut for that, right? What thickness would you recommend?
Thanks for replying and I never thought about that. The snails aren't gut-loaded just like you thought..I mainly feed them that because I don't want their beaks getting out of control.Are these snails from there freshwater tanks?
I'm not 100% sure but maybe they aren't getting the nutrients they need from these snails, unless these snails are gut loaded which I'm sure they aren't since they are pest snails.
I know some aggressive fish, like lionslfish, that when they eat live food from fresh water tanks, they can get liver diseases due to the fatty acids in the freshwater fish. I wonder if this can be the same with freshwater snails? Possibly.
