I have two frogs in a 3 gallon tank (Binga-female and Timmy-male.) Their tank is at 77 degrees. They have a lot of hiding spots in their tank a big cave, terracotta plant, beta log, two silk plants, bamboo shoot, and a cichlid rock. I've seen both of them all over the tank enjoying all of these feature. After I did a water change over the weekend and rearrangement of the tank decoration, Timmy's behavior has changed slightly. He is spending more time hanging out at the top of the tank. or near there sometimes with his nose/mouth in the air than he did previously. Sometimes he will be on the plants. I'd say he is only there half the time at most, he does spend a good portion of the time hiding otherwise. Binga is doing fine and I don't see any change in her behavior. In fact, they mated Monday and Wednesday (that is another story.) I feed them frozen bloodworms (Sunday night and Tuesday....) Should I be concerned?
