Carl was doing great. But then, my grandmother got me some Zebra Danios. I put them in but while doing so, some jumped out of the bag. I put the rest in the tank and saved the rest on the floor. After a day, Carl was looking lathargic. He was at the bottem of the tank not eating or really moving. I tried putting him in the 1.5 gallon to try to feed him and I would pick him up with the net to try. It wouldn't work. 2 days later, the danios started to die. Once they were all gone, Carl ate like a king. I was happy that Carl started eating but sad the danios died.
