so I found a bladder snail in my filter for my goldfish tank. the filter has 2 hob compartments but they both had 15 bladder snails eggs each. I scrubbed it and put the filters back in but there's still some tiny snails in the filter material. if they end up reproducing will it be the end of the world? I've only found 1 in my tank and then scrubbed the tank very well and haven't found any snails or snail eggs in the tank itself. will a population of snails in the filter compartments be bad or it it ok to let them do their snail thing?
