Me and Hubby went to plant smoothie and I saw they had a fish tank. It was a 55 gallon and had 3 LARGE Bala Sharks. Tank was plagued with algae and the poor balas were so skittish. There wasn't much decor in there either; not that it would make up for them having a tank too small for 2 large balas. Not to mention they should be in groups of atleast 5.
