Will they ever get used to it? I added a very small submersible filter, set to the lowest flow. It doesn't seem to bother my female ADF but the male acts terrified, trying to bury himself, won't eat, won't come out, not calling, etc. And he's usually the ham!
After three days of not eating, he was looking skinny so I just turned the filter off, fed them and he's pigging out.
Will he ever accept the filter? Is it worth trying another like a canister or should I just switch back to water changes? They are in a 20g long, just the two frogs, with a Zoo Med 318 filter.
