Yeah they do well in a school, if you could get some more he'll be happier, although they do grow pretty big. It depends on the size of your tank.
When I first got a bala I started with just one and he seemed so sad.... so the next day I purchased 2 more and that made such a difference in his behavoir. Of course now I am encountering other problems but at least he is happy with his 2 friends!
I have recently purchased 1 more and they seem alot happier. I have a total of 12 fish now. My tank is a 20 gallon one. Thank you for your help
I am certainly no expert but from what I understand you are going to be needing a much bigger tank. The rule is 2-3 gallons for every 1 inch of fish. The balas can get as big as 12 inches. Enjoy your new bala!
