Fish Fanatic
Something important seems to have been left out.
The lyretail gene extends the length of all the fish's fins, including the gonopodium on male fish. This means they are unable to mate. They will try but they can't quite do it. You either have to put some regular fin males in the tank to make the females pregnant, or else use artificial insemination. Yes, it is fiddly and can be dangerous - it's definitely a two person job.
Thanks that is what I was asking about. The female is pregnant so hopefully I will get some fry to make it from the bunch.
As for the fry, the tank's levels are at about .25 at most.
