I have had my male bullfrog for about four years. I put in the female about a year and a half ago. They live in a 55 gallon aquarium that has about 6 inches of water in it. I have an undergravel filter with a powerhead in one corner. There are two sunken ship halves in for housing/hiding, decoration, and for dry land area. The male has always been active. When I fed him he would jump at the crickets and my hand and such. For about the last three days he has not gotten out of the water. He is not active now and shows no interest in the crickets. He also is floating on his back for a while then kicks around and goes to the other side of the tank then floats normal for a while. I am not real sure what to do. There is not much I can do since when I try to pick him up he just kicks.
