A lady I got a chicken from a few months ago said she uncovered a nest of them on her koi farm and couldnt keep them around cause they eat the fish. Well we got one for free with the purchase of a chicken Ive had it in a 10 gallon tank with rocks that for like a beach leading into the water. Its about 1/2 water 1/2 pebbles. Thats it. I dont know what else to do for him. He seems so bored. His water isnt very deep and Id like him to be happy. Are cleaning rocks from the outside and putting them in there going to be ok? How should they be cleaned? How deep should the water be? Hes a little over the size of a quarter now.. And what is the proper diet for one? The lady gave me a can of shrimp and he eats them but they smell SO bad.. I think she said it was a slider belly...?
