Recently I have bought 2 Male guppies. (Einstein and Shakespeare) When we first got them they were acting natural and swimming around happily. Now shakespeare is the only one who is active and eats the most. Einstein just lays at the bottom of the rocks or under the filter. Ever time I first look in I think he is gone but then I see his little gils moving. He never eats very much either. Their water temperature is 77 degrees F. and it has always been since we got them. There is one live plant in the tank, we have changed the water Wednesday because the food got stuck in the rocks, we put the same exact things in the water. I don't know what's wrong with him and I am worried about him. If anyone knows what might be wrong could you let me know. Or if you need more info.
Thanks!
Thanks!
