MBU Not eating ....yet

[Jayzao]

I have had the same MBU in a 150G tank for four months and there are also two fronts and a Juli and a very small pleco in the tank.
She eats regularly and is pretty active. I have a 300 project tank for her set aside.
My water is always pristine as I test once a week and complete 2 30% water changes a week. I have a 30G sump and two FX5 canisters.

Friday she was lodged behind a rock and seemed disorientated so I moved her to a 20G hospital tank where she just floated in a trance.
Her color is great and she is active now but still will not eat when generally she eats twice daily.
Any ideas of what to look for?

Thanks in advance,

How can you tell the gender of a mbu puffer ?

Cannot, but my wife has always thought of her as female. And if that one fact endears her to a fish and allows me to spend a bit more sometimes then let's just call it "she"
