I have a Scribbled Rabbit, 4inches long, that I've had for over a year. Came to me at about 1 inch. He initially did well and grew fast. For some reason he has been losing weight, he looks very skinny even though he eats well, pellets and frozen. All of his tankmates are in good health and robust. He is not being harassed. Lately I've noticed he goes to the surface, gulps air and expels it out his gills.
Any thoughts?
