1. Make sure that the bottom of your aquarium is fully supported by your aquarium stand. If you have any gaps in the structural integrity of your aquarium, it is much more prone to breaks and leaks.
2. It is generally a good practice to purchase the largest aquarium that you can actually afford. A larger aquarium will be less susceptible to quick changes in the chemistry, and will offer much more stability.
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.
