Aquariums at Rubio's gone?

I noticed a couple weeks ago when I stopped at a local Rubio's for lunch that the place's aquarium was gone.

As long as I've been eating at Rubio's restaurants, each spot has had a moderately large aquarium with several varieties of fish. It's always been a pleasant feature, and of course children love to watch the fish swimming.

So, when I saw the aquarium was gone at the one Rubio's I visited a little while ago, I was surprised, but thought perhaps it was just being replaced.

But I stopped at a different Rubio's a little earlier today, and in that one also, no aquarium. Huh.

Just before typing up this post, I tried searching in Google and Google News to see if anything was being said about aquariums being removed from Rubio's restaurants. Despite using several combinations of phrases and words, I didn't come up with anything that seemed pertinent. I'm assuming I just wasn't finding the right combination of words, so I'm curious if anyone out there has seen anything online about this?
