1. When breeding angelfish, it is normal for the first spawn to suffer heavy losses and not make it all the way to the hatching phase. You should have the proper equipment before you start to breed angelfish.
2. Try to provide an environment that is as stable as possible, fluctuations in the aquarium can have a negative impact on the aquarium. Try to keep the temperature and PH levels fairly balanced in your aquarium.
3. Discus fish are very hard to care for, they have very specific care instructions. These fish are hard to care for but are very beautiful. However we recommend that these fish only be kept only by the advanced aquarium owner.
