Why is my Mbu sparring with its reflection

[Deep Blue Sea]

He seems to be attacking the glass whenever I turn on the light like he thinks theres another puffer there

why wouldnt he attack his own reflection?

 

[Deep Blue Sea]

well is it stressful for him? because after a while he has to lay on the bottom and rest

my mbu does the same thing not a clue why but i found that if the sides are covered and just the from left open he calms down alot

stress and adrenalin takes it's toll and is not sustainable ...

put a background on, should solve the problem.

Many puffers do this if there is not enough decor to interest it. Puffers are very intelligent & bore easily. Could you post a FTS?
