Rummies are naturally tight shoalers regardless of the size of tank, tankmates and water conditions. As for the red coloration, it is an indicator of good or poor water conditions. If water condition is very poor, the red pigment will subsequently fade.

Tetras do not use hiding places unless intimidated, terrorized or insecured but those serve to make them quite comfortable in their home.
My silvertips would attack them at first but have sopped doing it by now. They have actually become friendlier to each other. I would like to add some 7 black neons. It is a temptation. I hope it won't be too much for that tank. It does have hiding places now but nobody seems to use them.
