Ah alright, did you ever find a better option that the breeding net though?snazy said:Your tank seems to have a lot of cover. Get yourself a coarse sponge, not fine like in the picture. It won't restrict the flow.
Then make sure to feed some finely crushed flakes that fall slowly to the bottom. Platy fry don't come up to the surface, but tend to choose a safe spot in the tank and hang around there waiting to be served. Many will survive eventually. Unless you are after raising all fry from each batch.
If the fry are too small, they'll escape the breeder net. My cory fry all went into the tank once hatched as my net isn't very fine. I think there are finer ones they sell too.
How are those solid plastic box things? not too keen on that option but if it does a better job that this thing...
