The latest batch of goby fry have reached the stage were they traditionally pop their clogs. I’m a little more optimistic this time as they seem to be more robust and started to eat newly hatched brine shrimp rather earlier than the other batches. Nevertheless I’ve started to lose one or two. I have about 20 from 30 originals.
Here is a picture of a 17 day-old fry starting to show symptoms, note the ragged caudal fin.
I have a fifth batch in another tank and will gamefully try different things to keep the little blighters alive.
