Mini beta fish tank bundle includes, 4 mini filters, food, castle and fake plant decorations and mini tank. Tank has small cosmetic chip off bottom that makes no difference in anything and if it’s put in a certain angle it can’t be seen. This tank can hold one beta fish or a couple tiny tetras. You can get a mini filter at pet supermarket bring the filters 2 different kinds or when you feed the fish just one flake a day cause the more u feed them the ammonia in the water from there poop will kill them. The less u feed them the better. You can use the tank for decoration and feed the fish in the canal. Enjoy
