Bangaii Cardinal... Odd Behaviour

[Myka]

Not much you can do about it. My Bubble Coral killed my Bangaii. Do you just have the single one? This is probably happening because your Bangaii has reached sexual maturity. If you can get a really good photo straight from the side I may be able to hazard a guess at its sex, and you could try to find a mate for it. That would distract it from it's reflection.
