Hi my question is if freshwater clam and mussel infect your aquarium? I found some clam and mussel on my local lake this weekend with my son. so my ask can we keep them in my 135 cichlid tank and I said ok. but now 2 days later I notice all my cichlids scratching agains rocks if as they are itching. can anybody let now what the problem can be. I removed all clam already. any info would be great I scare my fish will get sick and die .
