I have a 29 gallon with 3 blue gouramis in it i reently purchased 2 slightly smaller golden gouramis and they were dead the next morning, they had bite marks all over them. What are some fish options for tank mates of my blue gouramis?
They generally mix well with most other fish of a similar or even slightly smaller size. However, if you keep only two of them, one will often dominate the other, sometimes to death. Keeping 3 or 4 seems to lessen the risk of this bullying.
