Glad to be able to help @FishkeeperLinz . Something else for you to think about is joining the American Killifish Association. I did and it was a great help to me. Well worth the $35 dollars annual dues. Right now they are offering a free starter pair for new members for shipping cost only. It's usually gardneri or Australe's. But if you can afford it get three pairs and watch them like a hawk.
