Aww that's a shame! Mine was other way, had a female for a while but no male. First one we added was in bad shape and he passed.csfishkeeper said:
Cs what an amazing picture of your peacock gudgeon! Does he have a lady friend? I wish I could get good pics of my two.
He does not yet. The girl I ordered with him didn't make it during shipping and I haven't had the opportunity to pick up one yet. My local store gets them on occasion and I've got a standing order for one once they arrive.
Second one was in good shape and female had a big belly by then so they spent the next 3 days in a boat/cave No babies came of it though unfortunately!
