Hi

I did have a very content frog and now any time there is a slight movement near the tank my frogs thrash around they look scared.
I recently bought a second acf frog my original one is about 10 weeks old and the new one is about 5 weeks old. There are two living plants in the tank and a pot like thing for them to hide in.it is out of direct sunlight, water temp is perfect, they are fed daily, the environment is generally quiet and peaceful just a bit of tv in the room but it isn't loud. I notice the smaller frog hides under the original frog quite a lot is that normal? I have a filter, i change part of the water every 3-4 days as these little frogs are so messy. Could they be jumpy because I introduce a new frog? When my first frog was tiny it was living with zebra fish for the first week, they have been removed so that they don't become a meal. He seemed calmer around the fish.
