I went to do my water change today, just like every other weekend, but I only saw one of my clownfish. The female is still in the tank, but I can’t find the male. I checked all around the tank, near the rocks, in the sand, in the filter, but I can’t find it. Is it possible my snails ate it? I...

Hello all! So about half a year ago I purchased some astrea snails, and have never had any issues with them, except for two of them would have some sort of string come off their shell. I’d worry that it was a vermitid snail, so I’d try to cover with with super glue, but they always seemed to...
