Tiger Barbs Behaving Strangely.

[barb218]

I have a 90L tank with:

5 Tiger barbs -1
2 Penguin tetras
5 Corydoras
8 Neon tetras.

But recently one tiger barb had a cut on it, and all the tiger barbs are now very shy and one died. They won't come up for food. and just hide away during the day.

Does anyone know whats happened to them?
Thanks.

Have you checked your water stats, especially with one dying? I'd say do a substantial water change, continue to check/test your water and monitor.
That aside just sit tight & see how things develop is all I can offer at the moment I'm afraid.
Hope all works out.
