Hello! I have a saltwater tank and currently have two Mono Argentus. I had three but the smallest one most likely became an eel snack . The two get along very well, I have never seen them fight over food or swimming space, but recently the smallest one has been acting weird. He keeps swimming up to the larger mono and kinda swimming on his side around him? He is perfectly healthy from what I can tell and the water quality is good. Im just curious as to why he is going this! Is it possible he is trying to convince the other to mate? Or is he just a doofus?(I say he for both of them but I do not know the genders)
