They all have in common that they give birth to live young and do not lay eggs like most other fish species. In the wild, live-bearing toothcarps eat insects, insect larvae, algae and anything else that can be eaten - they are not choosy. Depending on the habitat, algae with the small animals living in them often form the largest part of their food spectrum.Flakes or granules?Honestly: it's a kind of question of faith! There are only a few arguments for or against the type of food. If you use an automatic feeder like the JBL AutoFood, you MUST choose granulated food, as almost all automatic feeders are only suitable for granules. If an automatic feeder is due on your next holiday, get your fish used to the granules from the feeder RIGHT NOW. Some fish actually find it a little difficult to switch from granules to flakes or vice versa. Imagine that you have always eaten soft cornflakes and now you are getting wholemeal cereal for the first time.Probiotic or prebiotic?Probiotic foods, such as some types of yoghurt, contain live bacterial cultures to promote health, but only when consumed in larger quantities. Such foods, including probiotic fish food, can easily spoil and then have the opposite effect. The positive effect on health is, by the way, quite controversial.Pre- or prebiotics are "substrates that are selectively used by host microorganisms and impart health benefits." Scientists agree that they promote digestion and thus health. With better digestion, less is excreted and thus the water is less polluted, keeping the water cleaner and causing fewer algae problems.
