Tiny snail infestation... help me get rid of them!!
Lately my tank has been riddled with a somewhat daily snail infestation. Every morning I kill at least 10 snails (by squishing them), only to find another 10 the next day. They obvisouly came in on a plant that I didn't clean well enough, even though I rinse all my new plants well! The snails are tiny, about 1-3mm, and range from grey to black/brown, and they are a little see-through. The shell is round. Because they are so small I cannot get a photo of them (I found this on Google, the snails look similar Delicate Aquatic Snail Post Cards from Zazzle.com). They seem to only come out at night and during the day they burrow into the gravel, making them impossible to find! They really are annoying me, they've been eating my hygrophila, bacopa and some of my crypts, although so far my lace fern is untouched. My bacopa is all but destroyed, with just a few sad stalks with a little new growth on top remaining. So far I've tried a few things to get rid of them, including: leaving a lettuce leaf in a jar over night (also tried spinach) – this did not seem to interest them and there was nothing in the jar after several mornings; intense gravel vacuuming – this annoyed them and let me squish about 20 as they came out of the substrate, but otherwise they still remain; reduced feeding of my betta and shrimp – this seemed to slow the snails a little but they are still there! My tank is 30L, gravel substrate, moderately planted, filtered, heated, and home to a betta and several red cherry shrimp. My betta is fed twice daily, and the shrimp every 3-4 days – although at the moment I'm just leaving them squished snails to eat and not feeding them any extra at all. I clean my tank once a week, do a 50% water change, use Prime and Excel. Any suggestions? Unfortunately as far as I can tell Assassin snails are not available in Australia, and I'd rather not resort to harsh chemical treatments if it can be avoided. I don't want to harm my betta or shrimp in any way. What can I do to get rid of these nasty little kritters?!
