Hi there, i tried to breed angel fish but i can not get the babies to live, can you recommend how to go about to get them to live and how to feed them from day one
Thank you
Hannes
The angelfish babies just die or they get eaten by their parents? For new angelfish parents it can happen, that they eat their fry. However, if the angelfish fry die suddenly, it could be a problem with the water parameters. Test your water, and if the water is good, feed your fry infusoria, micro worms, newly hatched brine shrimp or vinegar eels. You can also feed them commercial fish food such as Hikari First Bites.
