1. It is never a good idea to hand freed a Lionfish. No matter how tame you think your Lionfish to be, they still have very venomous spines and should never be hand fed.
2. You should always thoroughly research the type of aquarium you are going to be setting up before you purchase it. Make sure you have the proper gallon capacity and shape that will fit in your home.
3. 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.
