Does any body know how to breed Marbel Hatchet fishes and how to recognize male and female please?step by step expalination will be appreciated.thanks.
Welcome to our forum! I don't have personal experience with hatchetfish, so I checked on Google. Some interesting facts about the species: they are jumpers, so cover your aquarium; they are schooling fish and do better in groups; males and females look the same, but a gravid female will sometimes show a big tummy; they spawn in bushy floating plants, and their eggs hatch in about 30 hours. Hatchetfish are considered somewhat difficult to spawn.
Since personal experience is always helpful, I hope another, more knowledgeable aquarist will provide additional details.
