    Hi, I got a group of Rhinogobius duospilus last year. One of the males came in very, very emaciated. Nearly dead. I was able to revive him, and he has thrived since then. He even bred recently, though the eggs didn’t make it. However, he looks very different from my other two duospilus males. The shape of his head is entirely different from that of my others, and his lips was very different. He was able to breed with the females, but I have no idea if the eggs were fertile. He is either a different species or he was deformed from whatever left him emaciated before he got to me.

     

    This is him (he’s a little washed-out right now. Usually the bands on his body are a little darker. The last pic is what he looked like when he arrived. I am proud I was able to save him

    Anyway, I’d love if someone could tell me what he is. Many thanks.

    Hi Aaron,

    it is a R. duospilus, but he is deformed. I think, this happend inside the egg. Perhaps something has dropped on the egg before it hatched.

    Actually, he should not have survived and that’s why he looked so bad, when you got him.
    Since you do not know how this deformation is created, you should make sure that he does not spawn. Otherwise he seems to live quite well.

    Thank you, Jutta! That is very interesting. I will make sure he does not spawn. I appreciate your expertise.
