Okay so on Thursday I bought a bag of Nothobranchius Guentheri killifish eggs, and hatched them, as something to do over the summer. There were about 15 fry that hatched, and they are all growing fine of BBS. The problem is though, I'm not quite sure what the mortality rate of killifish is, and on the first day, about 3 really tiny fry died. So far, about one has died everyday, and I'm not sure what could be wrong. Thankfully, none have died today, and they all have big orange bellies filled with BBS. Is this normal? Any other tips would be really helpful. Thankss!
