Hey, I have a 10 gl tank with a 1 1/2" ACF and 5 minnows. The bottom is bare with one piece of mopani wood, and whisper internal filter. I have been trying to feed him frozen blood worms, and frog, and tadpoles bits. The water disturbance is low, but it is a bit noisy. I heard this can stress out the frog. He just seems to sit at the bottom of the tank all day. I will eventually be buying some soft plants, but I am concerned the internal filter is stressing him out? What are your thoughts on this set up? I will get pictures up tomorrow.
