Hi there.

It's true that White's have different personalities. Hopefully that's all it is, but it's definitely a good idea to still observe them during the first few weeks. If you notice anything else (like not eating), there may be a problem.

I have had my two White's for almost 2 years and a year and a half, and the older one hid for awhile after I rearranged their tank. The other one loves attention.
