1. When you are removing a large ornamental rock from your aquarium, make sure to check all the nooks and crannies. Some fish love to hide in there and it is good to double check to make sure you donít leave one of your fish out of water.
2. Catfish sometimes require freshwater as juveniles and then as they get old they will need a more brackish environment. Make sure you read up on your catfish to learn what its needs will be when it gets older.
3. 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.
