New tank fish hiding

[Theneverendingcleaningcycle]

We have just upgraded our fish tank to a much larger one. After running the cycle we added our rosie barbs. However they seem really nervous hiding at the back behind some rocks. Is this normal? We only have 4 and have upgraded tank so we can have more as I read they do better in larger groups.

Totally normal for fish to hide when in a new tank. Give them some time to get used to it. And definitely get some more, schooling fish are much more confident and happier in large groups.
