1. Angelfish are normally very peaceful fish, in times of breeding they can get aggressive.† It is a good idea to only keep one pair of mating angelfish in the same aquarium, as more of them can lead to infighting.
2. 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.†
3. You should always research the different types of fish you are going to be housing together.† Certain fish can be extremely aggressive and cannot be paired with other fish of different temperaments.
