Liisa, I have 2 temminckiis and am anxious to know if I have a couple.
They are clearly different in shape but I can't tell the difference yet
because one of 4 cm has a wide mouth, but also a bigger bellie and a big head,
compared to the other one. It's also beginning to develop some very tiny
bristles. Other one is 3 cm and has clearly a slimmer head but a more round
mouth. Pectoral fin rays are about the same, how many rays should be spiky?
Thanks for your advise.
