Lovely fish, my two are about 5 years old and still going strong. I would rather have more, but I can never find any healthy looking ones in fish stores. They frequently get called sensative fish, but I find this true only of newly imported batches, mine were even hardy enough to survive the very high levels of copper resulting from the water company changing the pipes - when most of my fish died (even my 'hardy' zebra danios and guppies) As mentioned they do fly, and I lost one that way when the hood of the tank was left open. To prevent this, these fish really seem to appreciate floating plants like frogbit, or high growing plants like Vallis to help them feel secure.

My first set of hatchetfish died quickly because I think my tank was not mature enough, even though it was more than 2 months old. I am glad I didn't give up. I got another half dozen after a few months and they are doing well in my tank of Discus, Cardinals and Rummynose tetras. They seem to prefer areas in the tank with less flow of water. They hang around under floating vegetation a few inches below water surface. They eat fine pellets. When I feed the other fish frozen blood worms or even live Daphnia they don't seem interested. I would recommend them to anybody.

Marbled Hatchetfish seem to be particularly sensitive to pH fluctuations. My tap water has a pH of 7.0 but almost no buffering capacity. When I was trying to keep a specifically South American tank, my pH would tend to drop quickly because I wanted a pH at 7.0 or lower, but I didn't want to add a lot of wierd buffering chemicals to do that. Every time my pH would start to drop, a hatchetfish would die, until I was down to three. I got fed up with my South American tank and consolidated it into another tank that had a very steady pH of about 7.6 because it had a trio of yoyo loaches that left empty snail shells all over the bottom, and the three remaining hatchetfish have lived there happily for over a year. I think the lesson I learned from this is that a steady pH is much more important than the right pH, according to some books.

Tenho 5 borboletas strigata há 40 dias, num aqua plantado de 100 L com plantas de superfície. Ficam mais na flor da água, por vezes descendo ao meio do aqua. São lindos, apresentando reflexos dourados! Alimento-os alternadamente com: Tetra Min (que pulverizo na superfície), moscas de banana (fácil pegá-las na fruteira e são abocanhadas rapidamente por eles), Color Bits (que fragmento na mão, em pequenos pedacinhos que boiam algum tempo), Sera FD Daphnien, pequenas formigas, e flocos fragmentados marca Tetra. Assim eles têm alimentação variada. Consultei estudo de biólogo que estudou sua alimentação, e, realmente, concluiu que os insetos são a maior parte de seu cardápio (achou restos de 7 insetos no intestino deles, em média). Por isto tal forma de alimentar. Vamos ver a longo prazo como fica. Boa sorte amigos, com seus borboletas.
