Black Molly Acting Weird
I have two black Mollies in a 55 gallon tank that I am cycling. They have been in there almost a week now and everything has been fine until this morning. The bigger of the 2 Black Mollies has been hiding behind my rock sitting at the bottom. He timidly came out to eat, but he normally rushes to the top with his tank mate and eats blood worms from my hand. I think there is something wrong with him. However, nothing in my tank has changed in the week he has been in there. PH, Ammonia, Nitrites and Nitrates are all exactly the same since I got him. His tank mate seems perfectly fine. Any ideas what the problem might be?
Thanks for all your help!
