Cherry barb - swimming sideways

[utahfish]

Sustained swimming on side may be an inner ear issue.

Lol the fish has vertigo

Thanks - you say that a male/female pair would be better than a female/female pair?

You dont want to add another male. Cherry barbs do well in groups with a 1 male to 2 or even 3 female ratio. Having more males than females one of the males will bully the other to gain access to the female. Add more females to limit and decrease aggression adding more males than females leads to bullied tattered dead males.
