Was wondering if it would be "kosher" to put assassin snails in a canister filter. I have a spotted congo with a uppity attitude. If I throw in a few snails for him and he deems them to small, he won't eat them. Now I have 2 canister filters littered with ramshorns, bladder snails and more...
I just purchased a calcium test kit for my aquarium however I'm still waiting to receive it. It is for saltwater aquariums so what readings should I aim for for a freshwater aquarium to aid in the shell health for ramshorn snails?
