Hi. I'm new to this forum and stingrays (not a newbie with fishes). I decided to renew this thread, because I have the same problem with one of my 2 Motoros. yersterday I noticed that of them, male, about 25 cm in size, when lying in the sand, is breathing through one spiracle. Also the same side of a fish (as the shut spiracle) on top is not making breathing moves, is not inflated. Still the ray is feeding (about 3-5 earthworms per feeding time/ 3 x day), and during feeding time the closed spiracle starts opening again, but maybe a little less then the one, that is O.K. Also when feeding or moving, both upper sides are making breathing moves.
